So my 5 1/2 month old, Link has now decided that he should stop right infront of us when we are walking him and if you try to keep going he bites at our feet. It is very frustrating and annoying. We have tried saying "leave it" and using a negative marker (which we learnt in Puppy class). He doesn't do it on the whole walk only parts of it. We start a Level 1 Beginner Class on June 10th but was wondering if anyone had any suggestions in the mean time.
