@betterxthanxnew One of mine had the discharge,at about 4 months. My vet also said that it was normal and nothing to worry about. It did clear up by itself-just wiping. Neither one of my purebreds were spayed until one year old. No particular reason-and they hadn't gone into heat yet. The other 2 were spayed at about 7 mo.
I don't think they were given a pain shot,after spay-but honestly,I didn't ask. Over the years,I've had many female dogs,had almost all of them spayed,and they never had pain meds. to go home with. When they came home, they didn't act any different than they did before surgery, because they usually spent the night at the vets. My main concern would be for you to ask what kind of
anesthesia he will be using. That is the most important thing with a bulldog.
