Tonight my Brittany was bit by another friends dog. The other dog left a puncture wound on the back by the front shoulder. It hasn't bled much but there is a hole the size of the other dogs K9 there. My dog is acting fine, it just hurts her if I inspect it. Should I use hydorgen peroxide on the wound? Should I just keep my eye on it for an infection and if that occurs take her to the vet?
