A great buy. Our Mastiff, although still full of life, suffers from arthritis in his front legs/joints. Whilst causing pain and limping it does not stop him leaping and jumping about when the mood takes him. We try to reduce the pressure and stress on his front legs by trying to stop him jumping up onto and off things, such as his grooming table and the car boot. These steps have made life so much easier for both him and us. He is a big old lad but these steps take his weight without giving or shifting at all. I have to make sure that everything is set in place before bringing him out as he tends to go a bit mad on seeing them. His classic trick is to jump up onto his grooming table so that he can walk down the steps ! A good purchase, so glad that I found them online.
