My dogs don't wear collars around the house and in the yard (its fenced and I don't leave them out alone). I'd rather not get into details but Gunner was being "baby sat" by my ex and when he came home he had a MAJOR indent from wearing his collar 24/7 (maybe an exaggeration - but A LOT!). It's very obvious to me and catches my eye .. How can I get it to go away? I've been brushing him daily and he's had 2 baths and its still there. The hair isn't bald in the area because I've pulled the hair up to look but its an dent obvious dent. Maybe time and a few months of shedding??
