This is a sling for dogs and cats. I purchased it about 5 years ago, but I rarely used it because my dog didn't like it very much. It has a hook inside to prevent escape or falling. It's convenient when you go to the vet, etc., because you can use your hands while holding your pet when paying the bill. Size: Width 37 cm, Bottom width 16 cm Height (length when lowered) 60 cm Weight capacity: 4 kg
