This Toos concept is by Industrial Design students Jeoung Rae Kim, Shua Bong and Seunghee Lee, of South Korea's Hyupsung University. Collectively they call themselves Comma.

"As more people get older and have pets, pets have become like friends or family to older people. But most walking aids for seniors only have space for carrying bags or for the person to sit and rest, so it's hard for them to comfortably bring their pets along."

"To solve this problem, we suggest a new product that combines a pet carrier with a walking aid. It has a special space for pets and a seat where the person can rest."

As someone who is getting older, and who has recently had to put multiple infirm dogs to rest, this is certainly something I can and would use in the future. It is heartbreaking to see elderly dogs who want to be outside, but whose infirmities make long walks impractical.
