Last time my boy got bit, I made a salve of honey, and coconut oil with a dash of Niacin. Worked amazingly. I'd also suggest adding a small amount of vitamin c to puppy's food. Vit-c Is needed for tissue generation (low c is the biggest causative factor in arthritis), nearly every mammal with the exception of humans makes their own C. Increasing in times of need. I personally believe that adding a small amount to the feed will be a help. Small 50-100mg with food, too much C can cause a quick bowel.
Good luck, but don't worry dogs have an absolutely amazing "healing factor" to use the comic vernacular.
Here's some extra love to can give to Puppers. 💋💋💋🌈⚾💗💖💖
