Yes it is possible. It would be swollen and be have some bruising.
If it really is one of the testicles, then it isn't normal. that would be a failed neutering. The dog would still have all the urges of an intact dog, and still be able to father puppies.
The proper term for what you're seeing is the bulbus glandis. They appear when excited..they are very important for breeding and helping to tie with the female, but they are not the testicles and remain after neutering. Your dog was properly neutered (although if you don't trust the vet you should change anyway). No worries they should be there and are perfectly normal
An un-castrated or un-neutered male cat is known as being intact. In other words, they still have their testicles which enable them to breed female cats.
Sometimes they do, sometimes they don't. I think there are two different kinds of neutering: one where the cat keeps his testicles, and one where he doesn't. The male cat that I had when I was growing up still had his testicles, even though he was neutered. That cat died, and four years ago, when I graduated college and settled into my own apartment, I got two cats from a shelter: an adult male, and a female kitten. The adult male had already been neutered by the time I got him. And he does not have his testicles. I was not involved with the neutering of either of those male cats: the one I have now was already neutered when I got him, and my parents took care of the neutering of the other one, since I was a kid. So, I know there are two different kinds of neutering procedures, but I don't know much more than that, unfortunately.
it depends what vets you go to and what animal is being neutered.
Females are spayed Males are neutered
It is recommended to have your vet to take a look at it. It is not normal for a lump to be near the incision site.
"...I want them to live normal lives wout being neutered or spayed..." - What do you think a vasectomy is ! A vasectomy involves either cutting and tying of the tubes leading from the testes or complete removal of the testes themselves - either way your cat will have been neutered !
No, they just remove the testicles. It is painless, as the cat are in an altered state when the procedure is being done. Please spade and neuter your pets unless you hope to keep it intact for breeding purposes.
A neutered male will no longer have testicles. Bear in mind if your cat has just been neutered the testicles still may be visible. It takes around 6 weeks for the hormones to calm down, so the testicles will shrink over this period. A male cat has a larger gap between the anus and penis, whereas a female cat's vulva is situated closer to the anus.
technically they still can. however, after he has been neutered his desire or urge to spray goes way down. Typically neutering will help to stop the spraying. However, a cat that has been neutered before reaching sexual maturity (around six months old), it is very unlikely the cat will ever start spraying.
Testicles 'drop', at the latest, a few weeks after being born. If you cannot feel testicles in your scrotum, you should consult your doctor immediately.
