Our 5-month puppy LOVES Dog-Ma. He anticipates the days we’ll take him and races to the car (he normally hates the car!). We can barely keep him back as he runs through the gates to Dog-Ma! Before taking him, we often read about the gravel outdoors bothering dogs’ paws and were worried, but it hasn’t been a problem at all. Dog-Ma has helped our puppy socialize and learn to play well with other dogs. Highly recommend!
