Red parasite like rash or bumps on underside of dog underneath tail, inside of back legs and around surrounding area. What is this?

Did they come up suddenly?

Is she an indoor or outdoor dog?

What is her weight?

Is there any hair loss?

Is the skin itchy at all?

Is there any scale or flaky skin?

I had this finished and the website shutdown on me. My son found the dog this afternoon and she appears to be in very good health other than these red spots that almost look like flea bites, but are red and I was able to pull one off but couldn't tell what it was. They must be sore because she doesn't want me messing with the area. She has very short hair and the hair in the area is white and pink skin and I haven't seen any fleas. Could these be lice or mites? I haven't seen any more so maybe the shampoo killed them? No flaky skin, but seems to itch as she keeps licking or scratching with her back feet when standing.

Mange mites usually cause hair loss and bald spots and this isn't the typical distribution on the body where we see mange, so I don't think it is mange.


It sounds more like a hypersensitivity reaction which is pretty common and sounds like your description. It can be due to something like flea bites or just about anything they have been in contact with. You can treat this with an antihistamine and some cortisone cream on the area.


Let me know her weight and I can give you a dose of benadryl to try for a couple days.

She weighs 11 pounds. And I meant I haven't seen any "move" since the bath - I typed "more" above. Didn't know you could give dogs Benedryl. What strength cortisone cream?
Expert:  Dr. Debbie replied 7 years ago.

You can give her 12.5 mg of benadryl every 8 hours. Try this for two days and see if that takes care of it. You can buy the cortisone cream at any pharmacy, used for humans (is the same as for dogs). Buy the strongest one and rub it in the area. She may lick there and it won't hurt anything, but try to let it absorb well first.


If the rash isn't better in two days, I would see your vet to make sure something else isn't going on, or she may need a stronger steroid medication to clear it up.

To verify, you don't think it is a parasite? I have another rescue dog and three cats and I certainly don't need this little girl passing anything on to them.

Expert:  Dr. Debbie replied 7 years ago.

I can't be sure by any means, without examining in person, so it is difficult to say with certainty. But usually, a rash as you describe in that area is not a parasite.


Mange mites usually show up with bigger sores, bald spots and hair loss, and are more common around the face, ears and top of the body more so than underneath.


Again, I can't promise that it isn't a parasite, but from what you describe it sounds like a hypersensitivity reaction.


To be safe, you could keep her separate for a couple days to see if it clears up.

Thank you for your help. I feel better about it now.
