One of the most common ear problems in pets is due to allergies. It can be caused by food ingredients, pollen, dust or any other environmental irritants. Common symptoms of an ear infection in your pet due to allergies are inflamed itchy ears and sore paws, since the allergy signs affect more than just the ears. To help your pet, change the diet to a food that does not contain any corn, wheat or soy. Not all environmental pollutants can be avoided but you can provide as clean and dust-free an atmosphere as possible. If you see your pet excessively scratching its ears or biting its paws, contact your vet to have your pet looked at.
