My golden retriever was attacked by two stafford terriers today. The vet examined her and treated the bite wounds on her ears, neck and back. He said it's not the worst he'd seen and that we should check in tomorrow. But my dog started snoring and breathing in a weird way a few hours after we got home. When she drinks water it sounds odd, like the water is getting in her windpipe, and she drinks very little of it. she has never snored before. Should I be worried?
