Xena has been having this problem for quite some time now. It's her paws....she bites and licks and chews them...loudly, constantly...INCESSANTLY!! We've taken her to the vet for it and hes prescribed an antihistamine called hydroxyzine. Sometimes it works, sometimes it doesnt. We've tried the sour sprays that supposedly taste bad so they prevent biting...worked for one day, tasted like candy the next. She does it so much that her paws have become raw and sometimes they bleed! This also happens to her chin. She rubs it on the furniture, scratches with her paws...anything to get the itch and it starts bleeding. The vet said we have 2 alternatives now...steroids (not favorable...can cause liver problems) or a veterinary diet ($75 a bag...ha!). I've tried socks for the paws but she takes them right off! I bathe her about every 2 weeks so i dont think cleanliness is the problem...I'm out of options! HELP!
