Some high-energy, athletic dogs, unable to sweat, will work to the point of self-injury, so make sure you're able to recognize the warning signs of exhaustion
My three-year-old mutt sure loves cats. Mabel’s dominant breed is black-and-tan coonhound mixed in with some Lab, Weimaraner, and who knows what else. She’s never met one up close but she chases them with enthusiasm that I would really get a kick out of were it not for the fact that she often chases them into traffic. It’s happened maybe five times in the two-and-a-half years I’ve had her.
