The first of our special guest blogs by veterinarian Sam Westhead of the Energetic Panacea Clinic of Dubai. Spaying and castrating bitches and dogs is done for many reasons which I'll not discuss in this blog but will return to at a later date. However one of the first questions asked by the owners of a new puppy is when to neuter.

Male Dogs

For male dogs this is relatively simple: 6 months of age. The procedure can be done earlier or later, but 6 months is considered the optimum time which ensures the dog has both reached a moderate degree of physical maturity but is not fully sexually mature. He won't have developed some of the bad habits which mature dogs can get into (such as aggression towards other dogs, 'humping' the legs of your guests, chasing after bitches in season and cocking his leg in the house).

Dog biting is a serious offense in many parts of the world. If you feel your dog is getting out of control, and sending him to behavioral school is not helping, you might want to consider neutering him

Neutered male dogs are three times less likely to bite than intact males. It consists of removing the testicles of the male. While some might consider this method excessive, you might find that you have no choice in the case of an uncontrollable male.

Female Dogs

Female dogs are a bit more complicated.

Again six months is generally recommended but the question of whether to do the operation before or after the first season always crops up. My lecturer in small animal reproduction, a man who was a world leader in his field but very practical and down-to-earth, said it didn't really matter one way or the other but the important point was that all vets in the practice gave the same advice so as not to confuse clients. Sadly he died in 1992 and since then a bit more research has been done on the subject.

One of the main reasons we spay bitches is to reduce the risk of mammary tumours developing later in life. If spayed before the first season the risk is reported as being 0.5%. This rises to 8% after the first season then 26% after the second. By the third it doesn't make any difference: about a quarter of unspayed bitches will develop mammary tumours during their lifetime. Personally I think these figures are a bit high.

We see plenty of bitches which were spayed after the first or second heat and haven't gone on to have tumours. But this is anecdotal and I have not spent long enough time in any one practice to see the results of delayed spaying.

My advice (and I think most vets would agree) is to spay 3 months after the first season. A season lasts 6 months so we do it mid way through the cycle. The age at which this happens is quite variable and depends on a number of factors including breed, size and variation between individuals. And the length of the cycle can also vary quite a bit so some bitches can have a 4 month cycle whereas some might go 8 months.

If your new puppy gets to 8 or 10 months without having had a season then I'd recommend spaying anyway.

Bad Timing

Finally a word on when NOT to spay. We can still spay just as heat is starting or even mid heat if it's essential (though there is a slight, theoretical, increased risk of bleeding) but never during a false (phantom) pregnancy. This is when the bitch doesn't get pregnant but still produces milk (I'll write a blog about this at a later date- it's an interesting phenomenon) because they can become persistent lactators.

. . .

So remember when it comes to neutering and spaying, timing is everything! If you have a male pup, it is nice and easy, 6 months is the key. But when it comes to a female pup, accuracy is crucial, and always consult carefully with your local veterinarian to make sure you are spaying at the right time, the future health and happiness of your pup is at stake!
