Hi my pit bulls scrotum is bright red and about an hour ago he started getting a rash on his face. Is this an emergency situation?

These may be hives and if they have come up suddenly this is probably an allergic reaction. It could be to a range of things e.g. a food, insect bite or plant.if available, give him some dog safe anti histamine (e.g. 8mg Chlorphenamine) and an emergency vet visit would be sensible.

Redness and sore on one testicle, hasn’t been acting like it hurts, noticed it when I gave him a bath. Female dog was just in heat and I am not completely sure they didn’t mate.

Hello this looks like a cut. I would keep this area clean and apply triple antibiotic ointment to this area. Try to keep him from licking this area. If this does not start to improve very quickly, it would be best for your vet to look at this area.

Inflamed/ irritated testes and excessive licking. Little whimpering yesterday but today more energized and seems less irritated but testes look same

From the photo it is clear that there is significant inflammation and possibly an infection too. He may well have orchitis, which can be a bacterial or viral infection of the testicles. The surface of the skin looks a little ulcerated so we need to stop all licking immediately with an e collar. I would also bathe the area with cotton wool and salt water twice daily. A vet visit is essential as soon as you can.

Inflamed, swollen red testes. Excessive licking and whimpering on and off.

I'm sorry to hear this. Swollen testicles may be infected or inflamed or there could even be a torsion. Whimpering indicates pain. Your dog needs to be seen ASAP and the vet will palpate and may scan the testicles to determine what is going on.

Redness by his private area and his ball are very red It also he recently just started to have fleas so we started using this flea and tick spray and that’s when I think it started

Hello so sorry to hear that your dog is having issues . From the pictures this looks very severe and needs to see a vet. This could be due to trauma to this area. Your vet may need to do an emergency neuter.
