Hi Kevin- If you aren’t sure what she is allergic to your going to beat your head into a wall and kill your wallet switching foods to figure out what works. Trust me. If her symptoms mirror those of an evironmental allergy (my vet said licking the paws is the key one) you are better off going to a dermatologist and at least doing a consulation and going from there. Testing for enviromental allergies would be a good idea, but if you are worried about money at all, I would still at least have a meeting with a dermatologist to have him/her look at your girls skin etc. Thats what I plan to do.
To do a proper test for food allergies/intolerances you would need to conduct a very strict elimination diet. They can be diffcult and time consuming, but it’s the gold standard for diagnosing food allergies/intolerances. I would cut the Greenies out for now. You can try changing the food. My vet suggested a fish based food and so far its been working well.
