The yorkies in both my household and in my mom's have demonstrated a few patterns re: being hyper. On top of normal puppyhood hyper-ness, ours get predictably hyper following a bath at home (zoomies are prepared for by laying out towels for the racing, still-wet pups) and also right after eating certain foods. Could be the increase in blood sugar or it could be an allergy. For mine, I think it's blood sugar because one of my two is a picky eater and can allow himself to go too long between meals at times. My mom's pups, however, recently became much calmer after switching to grain-free food (Wellness).
My mom's yorkie female was almost intolerably hyper and bite-y when she was very young. Thankfully, she's much improved at 17 months. A basic training course we took together helped as did her spay surgery. (Her shorkie, however, is still like a land shark with her ever-ready chompers.) |
