This is a new object for my 8 year old dog so it takes some training. I put it on the floor flat out and just made her walk on it. I will continue to practice with her with an incline of two then three, etc, steps. It’s a lot of practice but we’re getting there. I am thinking of adding astroturf  as my Rhodesian Ridgeback’s issue is her back feet slipping on smooth surfaces. We are going for x-rays this week to see if something has happened to her hips or spinal column.
