I have a chihuahua w similar allergies that started around same age. She was on Blue Buffalo Life Source chkn/brown rice puppy formula and was doing well on it. Since she was gaining weight, Dr. advised transition to adult. BB Life Source ckn/rice:Was fine for a while, then allergies started-thought it was caused by her food. Had her tested for allergies via blood draw sample. Result: allergy to dust mites, fleas, and molds. But not the dog food. Great environmental improvements were made, along w an Rx for sublingual allergy gtt Tx.
Sx subsided. 2+ months to go. Still have to use Benadryl prn. She still has mild allergenic Sx. Which Dr. Thinks may be from Ckn sensitives causing IBS. Being managed w probiotics and Liquid salmon oil also helps both the IBS and any minor itchiness. In short, the allergenic blood test is best. Sublingual drops better than injections.
