Q. Rough collie neutured 2 months ago after having testicular tumour is heavily shedding his coat is this normal?
DR. ANDREA M. BRODIE, DVM
A. Usually an unneutered dog will shed twice a year, in spring and in fall when he changes his coat to suit the seasons. This is regulated by hormones stimulated by the amount of day light. When you take away most of those hormones via castration, then there is no more trigger to start and stop the shedding and your dog will shed all year, independently of the seasons. So this is quite a normal side effect of neutering.
