This wheelchair, made of lightweight and durable aluminum alloy, is designed for pets with disabled hind limbs or limited mobility due to age. With its adjustable design, the wheelchair can be modified without disassembly to fit your pet's body. Its detachable joints and easy-to-buckle accessories make it convenient for installation. As a pet owner, it's important not to give up on our furry family members, especially when they have disabilities. This wheelchair can provide a second chance at a happy and active life for them. Please keep in mind the recommended size specifications and use the provided tools and leash when installing. This wheelchair is only suitable for pets with hind leg issues and does not offer therapeutic benefits. We hope your pet makes a speedy recovery.
