the ramp in the pic looks exactly like the ramp i have. for me, it was a complete waste to buy it, b/c the gate on the X is so high, it makes the ramp too steep for your dog to walk up. my girl is only 4, and will not walk up it. mind you, i have never tried putting a food trail up it - not even sure that would work. see if you can get a pet store to demo one for you w/your X. i purchased the ramp thinking i had found the solution to getting my gal in (think i mentioned it in a previous post), but when i acually tried it...no way.
rooby, my dog, is about 95lbs.
