Thats amazing - looks like a wind up at first!
Like i said I dont go to that training any more, when the same man wresled my 3 month old puppy to the floor because she was figetting about her teeth being seen I thoght that was enough, she looked scared and shes very bold normally.
The happy legs are a bit pricey so I,ll keep going on the stacking at home with the word, shes very bright and shes doing well so far at the opens so she'll catch on - i hope
