I need to build a ramp for a 12 year old yellow lab so he can get up and down the stairs of a deck better...he's a good sized male who's legs are beginning to fail him. I'd guess the deck is 36"-40" off the ground. I'm looking for tips that'll make it easier for the dog....ie: best slope, traction tips, do's & don'ts...just about any insights from those who may have done it or seen it would be appreciated.
TIA!
