At times our dogs mouth are would get red if her allergies were active but mostly she’d lick open area on her skin & her fur thinned out. A simple blood test can tell you what your dog is allergic to. I don’t remember the cost but it was not an outrageous cost that I’d have remembered it. Living in a rural area, we did not have access to a veterinarry dermatologist. We did take our dog for allergy shots but eventually Just managed them through her diet. She did have environmental allergies too but when they were bad, she’d manage he time outdoors herself. Two important things to remember are: even though you may find a certain food that is working, you need to read the ingredients list on the bag every time. The companies sometimes change their formulas & the only ways you’ll know is by reading the bag, or by your dogs allergies flare up. Also, our dog was not diagnosed as being allergic to peas but the current trend is to add peas to the dog foods. I have read that a lot of the peas are imported from China and the chemicals used as pesticides & preserves are not good for your dog. Our dog definitely had reactions to formulas with peas in them. The blood test our dog had for allergies told us that in addition to various environmental allergies she was allergic to potatoes, peanuts, & soy beans. The test was accurate enough to make a significant difference in eliminating reactions & keep her comfortable. Good luck!
