My dog's testicles are exposed from a bite. Is it an emergency?

Your dog's testicles should have descended when he was a much younger dog. The fact that you're just noticing this now makes me very worried that something is wrong. He could have a torsion, mass, or infection. I would have him seen by a veterinarian as soon as possible. He may need to be neutered to resolve this issue.

Poor pup! It sounds like he was injured when he was outside, and if he's crying in pain, he needs to see a vet right away. Please do not give him any human pain medications, as many are toxic to dogs and can be fatal if given. The vet can treat his injury, and give him safe pain medication.

Neosporin will likely not be sufficient to hit infection if your puppy punctured the skin all the way through. Should the wound be red, painful and/or hot, you need to take your dog to a veterinarian for an exam and prescription antibiotics. Your dog could get orchitis from this which could mean that he needs to have the testicle removed in order to heal the infection.

Swollen testicle can be due to torsion, allergic reaction or infection. i would recommend having it checked by your vet ASAP, if the swelling is too large you will need to take him to the emergencies if your vet is not open today.

I've seen this one time, and it was a hunting dog that I suspect had a disease transmitted from a tick. Tick diseases can cause vasculitis, which means inflammation of the small blood vessels. It's not uncommon for the scrotum to be affected, as the blood supply there isn't great. Sometimes we also see it on the tips of the ears. This could be an infectious problem (from a tick bite as mentioned above) or an auto-immune problem. Also can't rule out plain old trauma, like running around in a field with prickly grasses and the like. Get him checked out to rule out serious illness, and to get some relief for what I'm sure is a painful condition.

I would recommend taking him to a vet as soon as possible. It looks like in the picture a hole has formed in the scrotum. This could be a ruptures abscess,trauma, neoplasia or parasite. The testicles need a exam along with the prostate. I would recommend a elizabethan collar to prevent licking until you make it to the vet.

This often happens when dogs excessively lick their testicles, then the skin gets infected and scabs over. I suggest you keep him from licking ( you can put an e-collar on him or a t-shirt or a baby jump suit, if you have one, and then take him to a vet this coming week for an exam. He may need antibiotics for the skin infection.
