Michele Hewett answered 12/17/2007 My Dog Has Recently Started Licking And Biting On His Legs Like He Has Fleas, But He Doesn't. What's Causing Him To Do This? Another good remedy for this is using anti-itch cream (like benedrel gel or gold bond medicated body lotion). I have two pit bulls that have real bad allergies and this is what I use. Good luck and hope your baby dog gets to feeling better.
