Sometimes, dogs can experience food allergies, which are most commonly caused by a reaction to the protein in the food, says Stephanie Lantry, DVM, a vet with pet telehealth app, Airvet.
“[Food allergies] can present in many ways, but they commonly cause itching of the ears and the rear end. When the allergies flare up, they cause the skin to become red and inflamed,” says Lantry. As a result, the dog ends up scooting to relieve the itching.
If you suspect your dog has food allergies, Lantry says you should talk to your vet about doing a hypoallergenic food trial to get a better idea of what’s going on.
