Working Dog Healthcare
Dogs of all ages can be desexed. Today it is common place for pups to be desexed as they leave the litter. This means that your farm dogs can be desexed by your veterinarian as pups. The procedure is usually brief (involving only one day at the vets) and the recovery period short (10-14 days). With early age desexing, you can better train and manage your farm dogs, preventing the distraction of bitches coming on heat and male dogs roaming.
Desexing before sexual maturity also ensures diseases later in the dog's life, such as mammary cancer, uterine pyometra and prostate disease are unlikely to occur.
Bitches begin cycling at 6 months but should not be bred from until after their 2nd heat (ie. 18 months of age). Male dogs are generally fertile from 7 months, some at a much younger age.
Vaccination is the only prevention for dogs against fatal diseases such as parvovirus, distemper and hepatitis. Talk to your veterinarian regarding appropriate vaccination schedules.
Viruses can spread within the dog population as quickly as the human cold spreads from person to person. Wild dogs and foxes can spread viruses to your working dog. Isolation on the farm is no protection. Spread may be by flies, car tyres, or the clothes and shoes of people. Some fatal viruses persist in the environment for many years.
Dogs can be vaccinated from 6 weeks of age for protection against:
This disease is common in working dogs, is highly contagious and in more than 80% of cases, fatal. This virus attacks the intestines, causing blood stained diarrhoea, vomiting with severe abdominal pain and weakness. Immediate veterinary attention is required as the disease can progress extremely quickly (ie. in the space of 24 hours) and is usually fatal unless treated aggressively early in the course of this disease. In very young puppies, the virus can invade the heart muscles, causing difficulties in breathing and death within a few hours.
It is not necessary to have contact with other dogs for this disease to spread to your dogs. This virus is so persistent in the ground over many years that the environment around an infected dog needs to be cleaned with potent disinfectants to prevent spread to other dogs. Outbreaks occur regularly throughout Australia - especially in summer.
A highly contagious disease which spreads to unvaccinated dogs of any age. However, canine hepatitis is more severe when dogs younger than 2 years become infected. Symptoms include high fever, depression and acute abdominal pain and death can occur within 24-36 hours. Dogs that recover may develop long term liver and kidney problems and can act as carriers spreading this disease to other working dogs for many months. Ideally all dogs that come on to or travel off your property should be fully vaccinated.
This disease is extremely contagious to all dogs of any age and often fatal. Symptoms can include coughing and sneezing, nasal and eye discharge and depression. Muscle tremors, fits and paralysis can occur later in this disease. As the virus attacks the nervous system the recovery rates even with treatment can be low and recovered dogs may have permanent brain damage.
Caused by several highly infectious diseases, this illness is spread wherever dogs congregate such as dog trials, saleyards and boarding kennels. Affected dogs have a dry hacking cough that persists for weeks and can result in pneumonia. This presents a major problem for working dogs. Vaccines are available including those that are given intra-nasally and act to directly protect for this disease within a week. However, yearly boosters are required.
Not recognised as a disease risk in most areas of Victoria but relevant to droving dogs and working dogs that travel, this disease is spread by the urine of rats. This virus is usually transmitted to dogs by contaminated food and water or by rat bites so dogs travelling to at risk areas will require a yearly preventative vaccination. Lasting protection must include vaccination at or after 12 weeks of age, even if initial protection is given at 6 weeks. Leptospirosis is an animal disease that can be passed to humans.
In short, as a minimum guideline all working dogs should visit your local veterinarian once a year and the appropriate vaccine cover can be selected during a routine health check. Worming can be planned for the year along with other parasite protection.
Hydatid tapeworms pose a serious health risk to humans.
Hydatid Cysts can grow inside humans who accidentally swallow hydatid worm eggs from an infected dog's coat. Avoid situations that threaten to infect your working dogs with this tapeworm.
- Hydatid tapeworms are found in all areas of Australia where sheep, kangaroos or wild pigs (which all act as intermediate hosts) are in contact with dogs. While rodents and rabbits can act as intermediate hosts too, they are more important as intermediate hosts for other tapeworms that are likely to infect dogs ingesting them.
- After eating hydatid eggs from pastures contaminated by infected dogs, intermediate hosts can develop hydatid cysts. Working dogs become infected with the hydatid tapeworms after eating hydatid cysts from infected intermediate hosts (eg. infected offal from sheep). For this reason, dogs should NOT be fed raw offal. Ensure offal is disposed of in an area where it can not be scavenged by dogs.
- Dogs can also become infected with hydatids if they eat infected carcasses (sheep and kangaroo in particular) while scavenging on the farm. Ensure that all carcases are picked up from the paddocks.
- Alternatively, keep dogs securely housed when they are not working. This will prevent dogs hunting rodents and rabbits which again can act as intermediate hydatids hosts. Use other methods for vermin control (eg. rat and mice bait, rabbit poison).
- Base your working dog diet on quality pet food.
- Dogs in Hydatids Tapeworm areas should be tapeworm treated every 6 weeks.
Roundworm, Whipworm, Hookworm and Common Flea Tapeworm
Around 80% of Australian dogs carry intestinal worms. This is not surprising because some adult worms can produce 20,000 eggs a day and some eggs can survive up to 5 years on the ground. Dogs are infected via uncooked meat, rodents and also through the skin, from larvae on grass (whipworm), or from fleas. Even ingestion of material in contact with the ground can be enough to cause infection. What is worse, intestinal worms can infest people too, particularly children in close contact with dogs. Dogs with worms may show tell- tale signs - poor or dull coat, anaemia (pale gums), diarrhoea, pot-bellied appearance, weight loss and tail skidding. You may see white segments or worms in the droppings.
Fortunately, you can stop worms cycling in your dogs with regular worm treatments.
Suggestions to keep worm burdens down in your working dogs involve:
- Control fleas - veterinary "spot on" prevention in summer is the most effective - see below.
- Clean kennels and sleeping areas regularly.
- Control intermediate hosts of worms such as mice and rats.
- Remove faeces from dog yards and around kennel areas.
- Worm and flea treat farm cats.
- Wash hands before eating - especially after touching farm dogs and cats.
- Ensure dogs and cats are fed quality pet foods and do not rely on hunting and vermin for nutrition.
In summary, all working dogs need regular worming. Pups should be wormed according to their bodyweight every 2 weeks from birth. Then from 3 months of age monthly worming is advised until the pup is 6 months old. All dogs older than 6 months of age require 3 monthly worming with a product that removes all worms including the hydatid tapeworm. Consult your vet for advice including product, dog weight and worming intervals.
Are you sick and tired of the dog stopping to scratch, chewing at himself and pulling his hair out all the time?
Act now. Although fleas breed rapidly in warmer months over summer, fleas on working dogs can be a problem all year. Working dogs can commonly get allergic skin disease from fleas.
Fleas can be killed and reinfestation prevented for a month with "spot on" treatments that are applied to all working dogs, pet dogs and cats on the property. Fleas are a continual threat so continuous control measures are necessary. Veterinarians can help you with effective, safe and affordable flea control programs.
The paralysis tick is found on the eastern seaboard reaching from North Queensland to Northern Victoria (ie. Bairnsdale and the coastal East Gippsland region), and can live on a wide range of animals, including humans and dogs. Native animals cause spread of different life stages of the ticks as can any people travelling to the area during the mid-summer tick peak.
The paralysis tick is grey in appearance like the common bush tick. It affects the dog by injecting a deadly toxin which causes paralysis of the legs (ie. weakness and losing strength in the hind limbs) and eventually progresses to respiratory and heart failure. Signs of paralysis are seen from 3 to 6 days after the tick has attached itself to the dog.
Recovery rates depend on how quickly you recognise the signs of tick paralysis displayed by your dog and seek veterinary help. Symptoms to watch out for are loss of co-ordination of the hind limbs (drunken appearance), change in voice or sound of bark, retching, coughing or vomiting and difficulty breathing. Progressive paralysis spreads to the forelegs. Some dogs can die very early in the progress of paralysis so seek veterinary help early.
- Help prevent ticks attaching to your dog by using veterinary insecticidal washes weekly, tick-collars, "spot on" treatments, sprays and tablets. These may be used in combination under veterinary advice. No single prevention is 100% effective and there is no substitute for regularly examining your dogs at risk.
- Avoid taking your dogs to the tick habitat during the tick season.
- In areas of tick infestation at the height of the summer tick season, dogs should be checked for new ticks at least every day, by looking in the ears, under the collar and around the lower neck area, between the dogs toes and around the tail. More commonly ticks are found on the lower areas of the front half of the dog's body under the forelegs, ears and neck. Ticks can be hard to see, although after 2-3 days of sucking the dogs blood, the tick will be about the size of a pea, with a flattened oval shape.
- Remove ticks immediately once found and save it to show the vet. Ticks do not have a head - only mouth parts and the toxin is contained in the body. To remove the tick, simply scrape the tick off from the skin with a sharp blade. Spraying a tick (eg. with methylated spirits) before attempting removal may make the process easier but is not essential and causes delays. Alternatively, you could use a loop of cotton pulled tight around the tick at skin level, and flick the tick out with a sudden movement. It is important to remove the source of paralysis and leaving the mouthparts in the dog acts only as a splinter - nothing more.
- Immediate veterinary attention will be required if the dog has difficulty standing. Do not wait to "see how it goes" as your dog will not recover without treatment if the toxins have damaged the dogs heart. Do not offer food or water as your pet may not swallow properly. Seek veterinary help urgently. Paralysis tick antiserums are available.
This is a skin disease caused by tiny parasitic mites, and can be common in working dogs. There are two forms of mange; sarcoptic mange (also known as 'scabies'), and demodectic mange.
Sarcoptic mites are transmitted by dogs coming into close contact with infected dogs or wild animals such as foxes and wombats. They can also be transferred to humans. Mites prefer to live on lightly haired areas such as around the dogs face, around the elbow, under the armpits and in the groin area. The mites burrow into the skin and cause an intense itch. Dogs will scratch and rub the infected skin until it becomes red and hair falls out. Continued scratching will cause skin to become thickened and crusty. Consult your veterinarian regarding treatment with insecticides, and prevent reinfection by ensuring all dogs on the property are treated at the same time. Simple topical "spot on" parasite control can be applied to eliminate this parasite.
Demodectic mites are found living inside the hair follicles of dogs. The skin of infected dogs will not be intensely itchy, and there will be few signs of infection other than hair loss resulting in large bald patches all over the dog. Veterinarians can provide appropriate "spot on" treatment that is highly effective in controlling this parasite and allows for the hair to regrow. Mild cases will generally clear up within 4-6 weeks. However in the event of secondary bacterial or fungal infection, further veterinary treatment will be required.
Heartworm is a very different disease from intestinal worms and is poorly understood by dog owners. Mosquitos spread this blood borne parasite so a dog can be infected without leaving the property. Heartworm is a parasite which attaches itself to arteries in the heart causing heart and lung disease and eventually, death.
Heartworm is difficult and costly to treat. Wherever there are mosquitos there exists the possibility of heartworm disease for your dog. There are many different types of heartworm preventions ranging from daily tablets to monthly tablets or "spot on's" and yearly injections. Your local veterinarian will offer the most appropriate treatment for this parasite for dogs living in your region.
These can cause problems by going down the dog's ear canal, up the nose, or penetrating through the skin (particularly between the toes). Grass seeds can also lodge below an eyelid or in hair mats on the coat (particularly in the groin and armpit areas). Seeds such as barley grass and spear grass seeds (which have awns) cause the most problems.
A dog with a grass seed in its ear will shake its head, scratch its ear and often walk with its head tilted to the side. Seek prompt veterinary treatment in such situations. The dog ear canal is shaped as a downwards oriented hollow tube that is several centimetres long so a seed can become well embedded inside the dogs head and the dog may need sedation or general anaesthesia to retrieve it. To reduce problems caused by grass seeds, dogs with floppy ears should have the hair clipped short on the inside of the ear flap and at the entrance to the ear canal.
Dogs with grass seeds up their nose will have persistent sneezing, and the best treatment in this case is to get veterinary help to flush seed into the back of the mouth where it will be swallowed or spat out.
Grass seeds through the skin often lodge between the toes, and are a particular problem for long haired dogs. During spring and summer, the hair on the paws should be clipped short to reduce the chance of grass seeds lodging there. Grass seeds beneath the skin must always be removed (this may have to be done by a vet) and the dog may also require treatment with antibiotics if the area becomes infected. Grass seeds ignored in the feet can be a permanent cause of lameness in the working dog as they can embed deeply into the feet sinews and remain as an annoying, painful foreign body much like a large annoying splinter.
Heat stroke occurs when a dog's temperature rises out of control, because it cannot get rid of body heat fast enough. Dogs pant to reduce their body temperature so a dog puffing heavily in the heat is seriously working to reduce his core body temperature. Overheating typically occurs on days over 35°C especially when dogs are locked in vehicles or tied up in an area with limited shade and no water. Working dogs can also suffer heat stroke if already carrying a high body temperature (eg. when unwell or carrying an infected wound).
Initial warning signs involve the dog panting rapidly with its mouth open and tongue hanging out, often with the dog reluctant to move or work. As the dog's body temperature rises, the dog will become weak, listless, and may have difficulty in breathing. Heat stroke dogs can drool excessively and may vomit or fit. If untreated, the dog will eventually collapse and die.
Dogs showing signs of heat stroke require urgent veterinary treatment. Immediate first aid involves wetting the dog all over (bucket or hose down) with water and moving the dog in distress to a well ventilated shady place with plenty of good quality drinking water.
Heat stroke dogs may require urgent veterinary attention.
To prevent heat stroke, ensure dogs always have access to water. Never leave them tied up in the sun, or in a vehicle (even when windows are wound down). Limit work and allow regular rest and/or swim breaks during extreme temperatures - if it is too hot for you to go out do not send the dog.
Dogs age faster than people. With the increased work load of working dogs causing joint wear and tear, working dogs in particular tend to suffer in silence. "Arthritis" of old age is seen as limping on and off with reduced activity and "stiffening up" in the working dog. Surprisingly, arthritis is not untreatable and many working dogs can return to full function with advanced affordable veterinary treatments. Many are simply added to your dog's daily meal.
Raising and training young dogs
New pups on the property need a full vaccination, worming and parasite control program before entering your farm. Contact your veterinarian before this new employee starts.
Young dogs need PUPPY formula food designed for optimum bone growth fed to them exclusively until they stop growing between 6 and 12 months of age. Supermarkets, veterinarians and farm trade stores can supply specially formulated puppy food in bulk for on farm convenience.
Daily food needs to be split into 2 meals until the pup is 6 months old.
In the adult working dog, good quality prepared dog food should be fed. Only cooked or frozen meats can be safely fed to adult dogs - raw meat/offal (especially kangaroo or deer) can be full of parasites. Feeding of these raw meats and offal to dogs can pass on diseases like Toxoplasmosis or Hydatids to humans on the farm.
Exercise must be restricted as the young dog's bones are forming and too much farm work (including jumping onto and off the ute tray) before the bones stop growing at 1 year of age can lead to poor conformation. Poor conformation can lead to early onset arthritis in working dogs and potentially limit their active working life.
Training needs to begin early in small regular short bursts. Positive reinforcement training will encourage the pup to co-operate and learn. Food treats, verbal rewards and training with a more experienced older dog will encourage desired learning over and above outcomes that are negative and result in some form of punishment. Dogs less than 1 year of age can have permanent imprinting from bad experiences. Socialise pups on the farm by allowing them to mix well with tolerant older dogs. Teaching the pups to accept tying up on run leads and penning at an early age will result in better farm routines and dog management practices from the start of the working dog's career.
Australia is home to many highly dangerous snakes. Dogs bitten by venomous snakes will initially be hyper-excitable, may have dilated pupils, develop muscle twitches and may stagger, salivate or vomit. However, symptoms change quickly as the poisoning progresses so with known or suspected snake bite cases your dog should be taken immediately to your veterinarian. Snake antivenoms are available.
Many working dogs are accidentally poisoned. Dogs are particularly susceptible to 1080 poisoning (that no treatment exists for), so extra care should be taken to confine dogs and keep them away from areas where poisoning programs for pest animals are occurring.
Other poisonings include: sprays being applied to pasture, insect infestations, and sheep jetting insecticide fluids and dips. Also of danger are snail poisons and mice or rat poisons. Proper separation of the latter from dogs is essential.
Bushfires and emergency evacuations
It is important to plan ahead for taking care of dogs during bushfires or other emergencies. For instance:
- Ensure dogs are identified with collars, tags and microchips.
- Have a place to send your dogs if you need to evacuate. For instance, family or friends may be able to help, or you can get together with neighbours to identify a safe place (with minimal fire hazard) for dogs in your area. You can also check with your local council to see if animals can be brought with owners to designated evacuation areas.
- Evacuate dogs as early as possible to minimise risk.
- Ensure you have equipment to move your dogs. For instance, labelled cages/carriers (large enough for the dogs to turn around in), leashes, a plentiful supply of food and water, and any medication the dogs may require.
- Under no circumstances should you lock dogs in cars or dog pens/cages.
- If in doubt contact your local council or veterinarian for further suggestions applicable to your situation.
