This wheelchair brought my elderly dog so much joy. Her back legs stopped working a year and a half ago and the doctors told us to put her down. Instead we took her home and I ordered this wheelchair. It changed her life, made her really happy and she continued to go on 3 walks a day until 15 years old! This was a game changer. Hoping it can change another dogs life. She was a shihtzu 12 lbs. This item is flexible and can be adjusted for size. Works for pugs and other dogs that are of similar size.
