These dog steps are designed to make your dogs life easier by helping them on and off of couches, chairs, beds, and more. They can be used anywhere inside and are built strong, with the same quality craftsmanship that goes into all Fandango products. They are assembled with short carpet on the steps so dog's nails will not catch. Small, medium, and large dogs can benefit from this product, especially older arthritic dogs with hip or back problems. Your dog will enjoy mobility around the house. This step will help them get around the house better and lower the chance of their falling and hurting themselves or compounding back problems. Steps should not be used as step stools for humans.
