We have a five month old sheltie puppy who is mostly adorable. But she has these totally mad moments sometimes when she charges around like a demon charging up behind you and attacking everyone's ankles and feet barking wildly. She still has some of her puppy teeth and it really hurts! I have tried everything the puppy manuals advise.e.g yelping (apparently this is what another dog attacked in this manner would do) pinning her down on the floor (as a mother dog would do to her pups) and shouting "no" loudly. We also shut her away in the utility room to let her calm down.
Lots of people have told me that puppies grow out of this nipping but I am just wondering when? I am worried that I will end up with a badly behaved adult dog. Has anyone else had experience of this and if so what else besides what we have tried did you do?
