My dog has very, very sensitive skin and any collar we get for him rubs the fur off of his neck, makes him break out in rashes that turn into nasty scabs. I don’t know what kind of collar to get him that won’t cause this reaction. Does anyone have any suggestion or places maybe online I should look? EDIT: I have been keeping the collar off of him and use a harness for walks. I feel insecure about leaving him without a collar, he is a new rescue and still doesn’t know not to bolt out the front door.
