My Retriever (8 months) used to be a really good little walker but in the last few weeks he is out of control. He pulls constantly on walks - if he sees another person, dog, squirrel, bird he just tries to take off - and he is getting so big he has nearly pulled me over several times.
I did puppy classes when he was really small but he found all the other dogs distracting and I got on better with him one to one over the park. But now he has regressed and I feel I need help. Ive persevered this week with shorter walks, confined to the park, not the street and had a little success re teaching the "heel" command but he still pulls like crazy if he spots something
Should I retry the puppy classes? Any tips for getting him back under control?
