my mom has a 4 yr old or so cairn who has bad allergies & anxiety, which makes him chew himself raw. my mom gives him 40 ML (liquid) of equate, which she chooses over benedryl due to price. he weighs 19 lbs. is that okay? unfortunately he'll still chew himself unless we give him a chew. chews seems to work perfectly, however i dont know if its healthy to give him chews all day long. i also powder him with gold bond body powder. seems to help, but he doesnt let me get to his face, which is noticeable. and we had been giving him grain free foods but his allergies/itching was the same. i believe if there were some chews that would be healthy to eat all day long, he wouldnt itch much. do you know of something?
