Pet's info: Dog | Chihuahua | Male | neutered | 1 year and 7 months old | 10 lbs
Hi! My chihuahua has a rash-looking area on his neck that just developed yesterday and has gotten worse today. He's been itching it. Do you know what it might be and if there is any way for me to treat it?

I am sorry to hear about your dog. It is possible moisture is getting trapped on the skin by the presence of the collar or something in the collar is irritating to his skin. I would recommend letting him go collar free when safe inside your home to let the area air out. You can try cleaning with a mild soap or dog shampoo and applying a hydrocortisone spray to the area. If it isn't improving then a vet visit is needed. I would also either wash the collar or purchase a new one. If he must have something on at all times you could try a harness instead of a collar to give the area under the neck a rest.

You may need to think about what his collar is made of and/or how clean it is if the collar is the one common factor. If he isn't broken out anywhere else that would make the chance of it being a food allergy or generalized infection less likely. Also, it may be advisable to clip the infected area so any topical treatments get on the skin itself more effectively. It may be worth another trip to your vet, or to another one for a second opinion.
