Hi and welcome to YT! I'm really sorry to hear that your pup is having such a hard time with allergies. Have you thought of changing his diet to Canine Caviar. Several people on YT have had pups with allergies that cleared up after putting their pups on CC. You might want to check it out. I would suggest you go to
www.caninecaviar.com and contact them for some samples to see if it will help. Heck, I immediately put our pup on CC when she first came to us just to try to avoid any allergies.
Good luck and I sure hope your baby gets some relief very soon!!
