Disabled Pets have either temporarily or permanently lost the use of some or all of their legs due to illness, injury or age. Several companies, such as Eddie's Wheels and K-9 Carts, specialize in making wheelchair-like devices for pets that allow them to stay mobile despite their disabilities. These wheeled carts can be a welcome alternative to pet owners who would rather not put their pet to sleep if they suffer from an incurable disease such as degenerative myelopathy, which paralyzes dogs' legs.
