My New Super Bionic Wheels

I have had some problems since I was a small pup with something called slipped discs.  Now whatever this things are have on occasion caused me to have some discomfort and pain, and difficulty walking.  My humans have taken me to dogtor for some medcinin and this has gotten better.  About a year ago, though, it appears one of these disc things appears to have partially ruptured and this has caused me to have some difficulties with walking.  People say I have the appearance of a "very drunk old man trying to walk down the street."  Now, I don't know what that means but I do know after I walk for a while my back legs get very tired and they just decide they don't wanna work no more and I have to lay down and rest til they feel like working again.  This is most annoying as I want to run and play.  With the upcoming great and glorious vacation in the cabin coming up and my plans to play in the big creek outside the cabin and go for walks on the walkin trails, I was somewhat concerned about my stability and endoooorance level.  I am happy to report that my humans have bought me some bionic wheels.  I sit on a nice seat inside this bionic contraption and walk just like normal, only instead of using my back legs, I have wheels.  This allow me to go most fast again when I am a walkin' AND I can now walk again for a very long time.  It is most exciting and I am looking forward to the vacation in only 13 more night-nights.
