Allergies happen when your pet’s immune system overreacts to something the pet ate or encountered. Skin irritation and itchiness come from contact with an irritant in the environment, a reaction to flea bites, or from food allergies. Some pets inherit allergies from their parents.
Even if you don’t know the cause, look out for these common signs of pet allergies. Some pets may have itchy ears or skin. Hives or red patches on the skin are other indications of allergies. Like people, your dog may sneeze or have watery eyes. More alarming symptoms include swelling of the face, nose, and airways. Severe airway swelling could result in anaphylactic shock. This is a pet emergency that requires urgent care. Without prompt administration of the right medications, your pet could die.
