What Is The Pink Rash On My Puppy's Stomach?
More likely it is a rash and needs antibiotics from the vet.
I do not know for sure. You should take your pet to a Vet. It may be as simple as having sensitive skin or skin allergies. If you are using commercial per soap, it may contain ingredients that are too harsh for your puppy's skin. Harsh ingredients can cause redness, itching, burning, inflammation, rashes, dryness, and more.
You may want to consider using a homemade, pet soap made with mild and gentle, natural, ingredients. It is an Au Natural soap, meaning it contains no added fragrances whatsoever. It is especially, good for pets with sensitive skin. It is so mild and gentle it can be used on pets that are pregnant or seizure prone. It is a healthful, natural, pet soap.
