This is a question that we are often asked by the community. Do your dogs have allergies? Do you have examples of how you can check for dog allergies? What are particularly dangerous dog allergies?
There are two common types of allergies in dogs: food and environmental. Dogs can be allergic to common ingredients in their food (the type protein being the biggest offender, but not always the case) as well as different things in their environment (plants, trees, dust mites, cats, fleas, etc.). Common signs of allergies in dogs are: scratching, recurring ear/skin infections, rashes on the skin and even vomiting/diarrhea (common side effects of food allergies). The only definitive way to know what your dog is allergic to is to do allergy testing through your veterinarian. However, you can always try eliminating common allergens at home and see if it helps. Sometimes something as simple as Benadryl is all your vet may recommend to treat, but there are allergy treatments if the side effects are severe enough.
