I'm really sorry about your dog. I was cutting a mat out of my dogs ear once and cut a chunk out of her ear by accident. Another time she got a big cut on her belly from jumping over a barbed wire fence and my husband wouldn't let me take hwe to vet until week later. By then took a month to heal. She's like my kid and I just cried and cried. I'll send positive energy to you your dog that all turns out well
