Oh, poor Tasha baby! I think you may be right, K9S. It sounds like she's trying to cleanse the wound more than it being compulsive behavior; especially if the licking started after the wound was already there. Chris posted a great link. And I wouldn't hesitate to call the vet to get some suggestions either. Maybe you could try spraying some bitter apple around the perimeter of the sore, on her fur? Doggies have big tongues and I'm sure she'd still get a hefty taste of it. Friends of mine whose doggies have had such licking wound issues either ended up with bandaged paws or an E-collar! Hopefully the vet will have some good suggestions! And p.s...My Cody loves giving foot baths too! Hugs to you Tasha!
