It is my very strong suggestion
dogs born with herpes virus NOT BE SPAYED BEFORE THE FIRST HEAT CYCLE!
Vaginal and sheath lesions can occur in these dogs. The lesions will
remain throughout animal's life, and no effective treatment has been
found for these lesions in spayed dogs. If allowed to have normal
heat cycles, even if they are infected, they do not show lesions
as adults. There are several breed exception to this: Mastiff and
Mastiff related breeds, English Bulls, and Golden Retrievers.
Below are pictures for lesions
in early spayed female dogs. (Sorry I don't have a camera for vaginal and
sheath photos.) Many vesicles can be seen on scoping.
These photos are of the external genitalia of prepubertal spayed dogs.
