Sure no problem at all. I can't really say how it would last on the long run and i used it only several times, but i bought it because it has some good reviews on amazon.

About the rollerblading - i bought these:

they have 84 size wheels which makes it easier to ride on harder surfaces, but what i do, is just leave them in my car, drive to the park and ride there

Ah okay, I'll definitely have to look into skates as a cheaper alternative instead of a bike. We have several parks and sidewalks not too far from here that would be better for rollerblading. I'll also probably just take them for a test spin and if they can handle these roads then I wont even need to travel which would be a huge plus! xD

You need an old Priest and a young Priest.

Well we still have a puppy so we can't bring him out on the hard pavement for too long, so a way to get out some extra energy is to put him on the treadmill at a good walking pace he loves it and sometimes hops on it himself when he wants to go on . It's a great way to get some extra energy in between going out, and also a great way to do it if it's too hot out or if you don't have time for a quick walk before you step out of the house.

however by no means should you use this as your only form of excercise as dogs need to be outside and given the oppourtunity to explore the outdoors and to run!

Aha I'll keep that in mind, thanks.

We don't have a treadmill but that does give me an idea for maybe some "back and forth" exercises I could come up with when there's a thunderstorm or something along those lines. (Maybe I could use our staircase, hallway, or even our coffee table etc...)
