Hi! I'm desperately needing a sturdy ramp for our elderly Dane/Lab rescue (she's about 90lbs). Have tried the cheaper ones and she's scared of them so really need one that's pretty sturdy. Unfortunately her hips aren't prevently her from being able to climb in my daughters bed (where she's slept since she was a puppy...our fam are foster failure champs :) would be so grateful if anyone could help! Thanks in advance (from Bella + the fam)?
