Hi all, I have been working with my dog Emma for the last probably 6 solid months on retrieving. She was doing GREAT. Every time I threw a training dummy for her, no matter where it was, she would find and retrieve.. Water, Land, you name it, she would go get it and bring it to my hand. I did multiple dog training a few months back and if she didn't make it to the dummy first, she would follow the other dog back and if it happened to drop the dummy, Emma would pick it up and bring it to my hand. It was like a dream, everything I could ask for. About 3 weeks ago she stopped. She will run hard for the dummy, and stop at it and sometimes sit there, just waiting... She will retrieve dummy's thrown and drop them short by as much as 25 yards, or as little as 5 feet. She rarely brings items to hand anymore. She leaves dummies in the field, and I just can't figure it out. I took a 2 week break from any training whatsoever to see if she was being overworked.. Nothing changed, still the same.. I am stopping today from any advanced training and am going to work on the basics.. Sit, wait, get, bring here.. Only at about 10 feet and in the comfort of my own home using a clicker. Any suggestions here? Is my dog just in a stage in her life where she is rebelling me? I've heard dogs can be difficult in their "teenage" years, but I just don't understand how she can go from never miss, to never hit.. Any comments or questions I will love to hear/answer, but mostly thoughts on what is causing this, and most importantly, if I can be overcome. Thanks!
