My sisters black lab is just about to turn 12 years old. And honestly we aren't sure if she make it to see her birthday in Januray. Her basic health is fine - it's just that she's getting older. So I let my sister use my OTTO STEP for Jenna since she is having a hard time getting in and out of her suv. My sister says Jenna and her other dog Jack use it to get in and out of her suv but my sister thinks Jenna needs a ramp. The step is exactly that a step and that's what is giving Jenna problems. Jenna can't step up or down like she did in her younger years. Does anyone have experience with DOG RAMPS? Any suggestions for a particular brand? Thanks in advance!
