My dogs don’t care about the bandage at all and it can usually stay several days. I change it if it comes undone or gets too dirty or wet. If the weather is really crappy outside I may use (sacrifice) a bootie to help keep it clean a bit longer. I’ve been scratched, scathed, and even been nibbled by my playful pup. It’s pretty common for dogs to scratch people unknowingly while they are excited. Nothing to worry about. Make sure you train him to be a bit more careful around people. Esp around kids. From my experience, my lab doesn’t play with kids the same way he does with me and my family. He is pretty careful that way. The causes of dry paws in dogs may be various. A thorough investigation may be needed so to be able to exclude the triggering cause and initiate proper treatment.
