Before the medical community identified alpha gal we veterinarians knew there was something about allergies in dogs that were triggered by meat. We were using novel proteins to keep them from getting sick...kangaroo, duck, potato, chicken, lamb and fish. 20 years later the physician biochemist identified the culprit that stimulated the allergy, the Lone Star tick.
Yes but I live in a non lone star tick state and have had 2 dogs so far that could not eat beef.
