We currently have a male puppy (he's a rescue, so we don't know an exact age, but probably 7 or 8 months old), and (unexpectedly!) will be bringing a rescue bitch home within the next week or so - she is 8 years old, and has been spayed.
We will be castrating our boy eventually (he is never let off lead at the moment, etc), but were intending to wait until he was slightly older & had been through puberty, etc.
However, now we will be getting the girl, I am not sure if we need to bring that forward? Will he try to have sex with her? Obviously if she's spayed I'm not worried about puppies, but I don't want to bring her into our house to be sexually harassed by a much younger dog! I don't know if he'll bother if she's not in season, etc?
If anybody knows, that would be really useful. It isn't a money issue or anything to get him done now (and we will if it's the best thing), but obviously I have been aware of the potential health issues of being too early with the operation.
Thanks :)
