Hi, Recently, Kai has been too easy to excite. When I play with her, just starting to run causes her to whirl around, and bite my arms, or if I'm a head of her, she jumps up and bites my shoulders. It really hurts! Also, when I'm playing tug, and I ask her to stop, all of a sudden she starts to growl, so when I take it out of her mouth, she jumps up and bites at the same time, with her teeth exposed and growling. I'm sure it's play, though, because she's got very lose body language, unlike the rigid body language an aggressive dog would have. Anyway, she's gotten fractions of an inch from biting my face today, and that caused me to worry that maybe she might get over exited and bite a smaller child. SO, I was wondering if anyone had tips on how to keep Kai from getting exited like that. Please, though, don't say "Slow down.", because Kai completely loses her mind when I do that; and it causes a complete biting frenzy. Thanks!
