Because Tebow (aka Fatty Arbuckles) has gotten so heavy, I had to do something. Reviews all over the place, stores, forums, etc were discouraging, I gave it a shot. I bought a Trixie ramp from Chewy. I first placed in on a short cedar chest-18" high-and baited him. No problem. (He's a fool for bacon flavored soft Milk Bones.) Moved it to a 21" high chest. Super! Tonight it went on the SUV, bumper height 25" which makes the ramp rather steep. I kept a hand on the top to make sure it didn't slide off the car. Ahhh the Milk Bones did the trick! I had to slow him down lest he slide too fast or put a foot over the edge. We don't want a bad experience to foil this success. He must've had fun because now he just emptied the box of extra blankets and beds and is bouncing all over. I tried to upload a video but an .mov extension is not allowed. I did figure out how to get a screenshot of him though. Now has a YouTube link!
