Recently, I posted a question about my puppy biting it's foot. One of the answers said allergies are common in Pitbulls. My puppy itches at her collar quite often. She has a red spot on her neck that resembles a rash. It's only on one part of her neck, and not all the way around where the collar rests. I can't tell if it is just small cuts she may have caused while itching herself or an actual rash. Once the collar is off her, she typically does not itch there. She also likes to itch at her harness we use to walk her occasionally (which is 100% polyester).
You can see she scratches at the collar a lot. Can dogs be allergic to these kinds of materials? The collar is like a fake leather with little metal studs. Her collar before was like a strap that clipped together which she also itched at. Is it possible she just dislikes collars?
She does not have fleas.
