Dog gym? Oh yes… it’s a thing. For all those lovable pooches who need to apply what they learn in dog school during the biting cold of winter or the sweltering heat of summer, there’s the dog gym: an indoor space with treadmills, balance balls (for doggie pilates) and much more. And of course, for all the obese dogs out there, a gym membership is a great idea. Just remember… paying your dues isn’t enough: you actually have to go!
