Now, the new problem... now that I've been letting her off leash in our little neighborhood park she went from happy rompy dog, to being a poo vacuum in a matter of a few days. She won't even play, she gallops from one poo snack to another, and wolfs them down like a pelican w/ a sardine. It is so gross! I'd love recommendations/experiences with dealing with this habit. One trainer recommended a plastic pinchy training collar, two others just said to get a muzzle and that you can't train it out of them. I'm wondering if the "leave it" or "drop it" will work???
