Behavioral issues with male dogs, in particular, make this a standard minor surgery
for most male dogs.
On balance, it appears that no compelling case can be made for
neutering most male dogs, especially immature male dogs, in order to prevent future health problems.
Older male dogs have an extremely high chance of developing prostate disease — such that
most male dogs will at one time experience some problem, but unlike in humans this is very unlikely to be cancerous.
After surgery,
most male dogs are asymptomatic within 5 - 7 days and the prostate gland returns to a more normal size within 21 days.
Sutures: In almost all situations, female dogs, female cats, and
most male dogs will have absorbable sutures in the incision, which will absorb on their own over the next 1 - 2 months.
Most male dogs and some female dogs who scent mark raise a leg to urinate.
Most male dogs and cats are ready and willing to reproduce by the time they are six to 12 months of age.
Most male dogs are eager to play by the day after surgery but, to keep the incision intact, it is best to restrict the dog from boisterous activity.
