Hello I’m new my frenchie is 6months old and have been walking to heel training for over 3 months once or twice a day with chicken/cheese/ liver cake/dried sprats and cocktail sausages varied and sometimes he does this so well other times he doesn’t seam interested no matter what high value treat I’m using, if he sees a person he pulls terribly and if sees another dog all he’ll breaks lose and he barks like mad. Any ideas where I’m going wrong would be greatly appreciated.
