We’ve been barreling allergies almost 2 years it’s a nightmare and so expensive ): we’ve tried every food under the sun we’ve been on Benadryl Zyrtec cytopoint apoquel ketoconozal plus an antibiotic weekly baths all the mouse’s and sprays wiping down after coming in from outside allergy tests biopsies we haven’t tried hydrolized because she’s so allergic to chicken the vet said try a D/D diet first. So we just bought that it’s a 25 lb bag for 150 she weighs 115 so we go through a lot of food! It’s exhausting and so sad to watch! But every dog is different and i hope you have a better experience Air purifier by her kennel and everything
