Let my puppy Claire out and then let her back in a while later. Bout an hour later her face was swole up. Looked like a baby copperhead or water moccasin bit her on the snout because of the two holes really close together. The vet shot her up with steroids, penicillin, and sent us home with an antibiotic just in case she gets an infection. We use a country vet so they've seen their fair share of this stuff. Luckily only $107 for all that so I'm happy about that but my girl is gonna get what she needs no matter what. To my knowledge this is the first dog I've had over the past 30 years that's been snake bit. She does love to hunt. She's full grown but looks like a Lab that's only 50% the size it should be with some subtle Pit Bull facial features.
