My Frenchie, Cooper, is about 2, I am third (maybe even 4th) home. I try to take him on walks and he pulls on his leash so hard he pulls the pads off his paws to where his feet are bleeding. He now has begun lunging and growl/barking at people to the point his hair stands up on his neck and back. This have never been issues before but now they have come up. We have done private training. And I am considering doing another training session to hopefully correct some of these things. Positive reinforcement has not been working. HELP!
