Puppies are often in contact with the ground, have sensitive skin, and don’t have fully developed immune systems.
For some, this can be a recipe for a puppy skin infection called a pyoderma. Pyoderma infections look like little red pimples and are similar to impetigo infections in human children.
If your dog appears to have little red pimples, particularly on her belly, consult your vet. If you notice a rash or pimples on your puppy, go see your vet. Treatment is simple and effective.
