Black sore near anus.

Hello Dr.Marie (I am SO grateful for you!),

I have had my two dogs (same breeder) since they were six mths old and have never had this happen. Feces does get trapped in their hair but I check each time they go and clean their bottom if nec. I had a 3-day migraine and must have missed a piece on my male to the side of his rectum. I feed them green beans and raw carrots for treats so they haven't seemed to have bowel issues or anal gland issues.

Yesterday, I noticed he was chasing his tail so I checked his anal glands and found a stuck piece of poo to the side of his anus. I put him in the bath and kept cleaning it with a cloth and realized it was no longer poo and actually his skin. It is dark so I thought mabye a scab? I put peroxide on it and cut the hair off of it. Now, when he goes, I clean it with a wet cotton ball and then dry it with tp and then put peroxide on it. He has stopped chasing his tail since I have been doing this. I know you can't see it, but does it sound like a sore due to the trapped poo on his skin? It isn't oozing pus or blood and from what I can tell isn't red. I think I am seeing a dark scab? Is peroxide the best thing to use? I have antibiotic creams too? I was wondering what would be best to treat it and how long is it ok to treat it myself before I go to his vet?

Thank you, Diana. A heartbroken mom!!

Thank you, Dr. Marie! I will stop the peroxide and anti biotic cream. It is on the left side of his bum and about 1 and a half 1/2 inches down to the side of his anus. Does that still sound like an impaction or abscess? I was wondering if at any time I should use a q-tip to push gently around it to see if has pus or should I just use visual eyeing of it and noting his behavior about his bum like chasing his tail? His is white and skin is pink so his skin is delicate. Thank you again. This is my last question!

Thanks, Dr. Marie,
I am going to just schedule a vet appt for him tomorrow. I don't want to risk an impact. Thanks, again!
