We have 2 female rescue American Bulldogs, one Johnson (English bulldog type snout) one hybrid (pitbull type snout).Typical of the breed, they love their people but don’t do well with other dogs, especially each other.They’re kept separate but there was a miscommunication recently and they fought, and in less than 60 seconds they did about 4K$ worth or damage to each other. So when they are on the same floor of the house now (still separated by doors, rooms, etc) they are muzzled.They don’t love it but I don’t love paying 4K$ in pet bills and having my babies cut up so like I tell my kids everybody’s gotta make sacrifices in a family sometimes. Theyre learning to accept it (very stubborn breed Id guess most breeds don’t take as long).The XL Rhodesian Ridgeback male mask fits the Hybrid very well. She can’t get it off despite doing everything imaginable to try for a few days in the beginning and a to play occasionally.None of the available options fit the Johnson because of the shape of her head, but I kind of thought that might happen and was trying this before going the Hannibal Lecter route with the full mesh head cover with tongue and eye holes.She can’t talk of course but I suspect that since she now looks like Jason from the horror movies I think she’d have rather made this muzzle type work lol.Some reviews I’ve read for muzzles take off because the dog can’t eat or drink in them so I think some people might over utilize these. They’re tools to enhance the lives of the dogs by allowing them to be in situations they enjoy but otherwise wouldn’t be allowed in.Between two dogs that would literally kill each other in less than 5 minutes if they could, they need to be muzzled maybe 1-3 hrs a day max, many days not at all (after they’re used to it, initially they need to learn to accept the muzzle and stop trying to pull it off so I leave it on longer until they do).If your dog is in a situation where it needs to be muzzled all day your dog is probably not where it needs to be. Find a different room/location to keep the dog where it is happy and not surrounded by things it wants to bite.If biting you or your family is the issue do not rely solely on these muzzles for your safety. Dogs need the perception of a dominant owner so they can relax and enjoy life, find a trainer who knows your breed or you are putting yourself and your dog in a situation that will end with someone getting bit and the dog being put down. I’ve seen it too many times.
