If you aren't going to breed from your dog, have him/her desexed.
Thousands of healthy dogs are euthanased (put to sleep) each year in Australia. This is because not enough homes can be found for them - we have an 'over supply' of dogs.
Many dogs are bred by accident, because owners don't get around to desexing them.
You are less likely to forget to desex your dog if you have it done as soon as the dog is purchased or obtained.
In general, dogs can safely be desexed from three months of age. Desexing at a younger age can be less stressful for puppies than it would be for older dogs, and they may recover more quickly.
Along with helping to prevent dog overpopulation, there are many other benefits of desexing dogs. Desexed dogs can be better behaved and less likely to roam. Desexing pets can also prevent them from getting certain types of cancer.
Your vet can give you further guidance on desexing your puppy/dog.
