Well I think I will have to stop skating Whit
The last few times I have taken him, after his run I noticed bad scrapes on his pads on his rear paws. My boy just takes off with so much torque and power, that he must scrape them. He didn't hurt them at the same time, thank god, but I noticed him walking with a limp and not using a rear leg. That's when I saw the scrapes
I'm kind of bummed because its one of the only times where he can run as fast as he can for as long as he can. But I would only do about 2-3 miles max. It was super good cardio for him, but I don't think I would risk him hurting his pads again because that means a whole week of exercise is down the drain.
My advice would be to get some good speed going before you fully let your dog take off or teach them to start off slow and build up speed. My boy just goes hard the entire time, he's got some good lungs haha
