This Petstep HalfSTEP Pet Ramp is just what we needed for our 5 month old Shih Tzu.  Poor thing is so short and close to the ground that she can not jump high enough to sit on the sofa or see anything other than ankles and feet. With her new ramp, she is able to get up in bed, bound up the deck steps and set and romp on the sofa.  She took right to the whole ramp concept and is a master at flying up and down it.  We like that it is durable and light enough to put just anywhere for her.  Great product for short puppies and dogs who want to get to a higher level.
