A dog bite is worse than its bark
Some problems you can deal with yourself and some you need to consult your vet.
If your dog is bitten by another dog, the wound can often become infected. Especially if it breaks the skin. It’s not necessarily an immediate emergency, unless your dog has multiple serious looking injuries. However, your dog will need to visit the vet within 24 hours, to assess whether antibiotics are necessary. Prior to your visit, it’s advisable to clean the wound with antiseptic lotion.
