Had my Corgi get in a dog fight I pulled him out of forty years ago. He inadvertently bite through my hand. Nasty wound and I went to the ER and got heavy antibiotics. Took a long time to heal
I had a small mongrel (Spots) when I was a kid who got into a bite fight with a much larger German Shepherd who left bite marks on Spots. We took Spots to a vet, more for the fact that she went into shock than the physical bites. While in the vet’s waiting room, with Spots on my lap, she suddenly leaped into the air and starting snapping in all directions. Luckily nobody was bitten. The vet gave her a tranquiliser and when Spots woke up she was calm again.
