	Concerns about Castration Q: Dear Vet We have 2 miniature wirehaired Dachshund pups (both dogs) that are 6 months old. We have been told by a friend that they should be castrated, I think that’s what it's called, because as they get older they will start to fight and it has been known for the strongest one to kill the other. It this true and is it necessary for this to be done? Does it cause any after effects? and what age should they be when it needs to be done and how much does it usually cost? Please let me know if you require any further information. Thanks Andrew Holden

A: Dear Andrew,

It is true that sometimes, when 2 brothers are kept together, when they reach puberty they may fight in an attempt to obtain the upperhand. This is an expression of the normal behaviour shown by male dogs in attempting to become "leader of the pack".

I have known cases where 2 litter mates who played happily all through puppyhood and then became deadly rivals once their hormones took over ! Similarly, I have known cases where this has not occurred to a noticable extent. It seems to have a lot to do with how equally matched the two dogs are in size and weight. If one is significantly stronger or more aggressive, he will quickly establish dominance over his litter mate and peace will be restored as the weaker dog accepts his "place" in the heirarchy !

So, if your 2 dogs are very well matched, then you may have problems, but you could wait and see what develops. sometimes it is best to just castrate the less dominant of the 2, to emphasise the difference between them and so avoid conflict. Although, we normally recommend castrating dogs anyway for variety of reasons.
I have not known 2 dogs to fight to the death.

They can be done at any stage from 6mths on, and the price depends on the weight. Your vet could advise you on that.

Hope this helps,

Maeve Moorcroft,
