Taking puppy out for a walk (12 weeks) and he jumped up and bit his leg. He's quite smitten with trousers, hanging down stuff like dressing gowns, dresses etc and wants to bite them and play tug of war. NB. We do NOT play any tug of war games with him. Sometimes he lets go when we say LEAVE IT or NO but no matter how we try to distract him with proper chew toys, he won't leg go of things he is not supposed to bite.
We brought him straight back from walk and crated him for 15 mins. About to go out again now.
Any other useful advice on how we deal with this please?
