My dog has hair loss, red patches, and swelling. Is it allergies?

Updated On September 23rd, 2025

Pet's info: Dog | Border Collie | Male | neutered | 6 years and 7 months old | 45 lbs

My dog is losing all his hair and he has red patches on his chest. He also has some swelling around his bottom and under his arm pits. I've been giving him Holistapet CBD oil (oral), Vet Organics EcoSpot Hot Spot Dog & Cat Spray, and I bathe him every 4 to 5 days (if he smells). I'm going on a month of this and I am not sure if it's allergies or something else. He doesn't dig/scratch himself anymore. I feel like a bad pet owner. :o(

This actually looks very much like a flea allergy dermatitis to me. Of course it is impossible for me to diagnose via the internet with one photo. I am all for owners trying things at home for their pet before going to the vet as long as the animal is doing otherwise well. If those home treatments are not working, then I suggest you get Riley to your vet for an exam so you can figure out what is going on and get him the appropriate treatment. Best wishes.
