The biting of the ankles will outgrow itself if you are persistent with the command "NO". Eventually he will realize to put the two together. Pasquale goes nuts with his toys...he shakes them like a mad man..but as soon as i say NO...he stops. He really didnt start catching on to things til he was 6 months...so your little one may still be young. Pasquale is now 1 yr and 3 months and he's the best dog i've ever owned...give it time. Dont get discouraged! Keep up your good mommy skills!
