I used to feed my furkids the Nutro lamb and rice (Natural choice) and my Lexi was still so itchy... I had to give her Benedryl (Advised by my vet).. I recently switched their food to Dick Van Pattens *Duck and Potato formula* for allergy's. What a difference.. Its been almost 3 weeks.. and Lexi has been so much better.. No more hot spots.. or her scratching herself so.. that her hair would come out..:-)
Just thought I'd share my experience.. Hope this helps..
