I tried posting this in treadmill post but got no responses. What treadmill does everyone use? Do you use one meant for dogs? I found some but they are all 1000-1500 or more for large dogs. I need to get one soon since when it is -25 and lower I cannot get him enough exercise.

We just use a cheap sports authority treadmill. Couldn't justify 1000 for a dog specific one over 250 for one I can use too. Get one with the longest stride you can. Ours is a little short and I'm wishing I bought the next size up. With the shorter stride, Harry gets up to a decent pace (5mph) but he really wants to trot along at 6-7mph.

How long is yours?  I am thinking the same as you.  The human treadmills should work for the little he will use it.  But he is a big boy at 26" tall / 70lbs and growing.

Our's has a 50" walking deck. From how Harry runs on it, I would say 60-62" would be great, but no idea if they exist or not. The biggest problem is his attention span still isn't 100% so he wanders forward and back on the treadmill. Another 10" would allow him to catch back up before his back feet fall off and also allow him to get closer to a full running stride for the higher speeds.

I just have a person one. I haven't used it with the puppy yet but I used it with our foster puppy and it worked just fine. I would have to measure it to see what size it is but it's super old and works just fine.

Mine was $30 bucks from a garage sale Best find ever! Rig LOVES his treadmill! haha As long as the dog fits on it and it works properly, you're good to go!
