I am not sure if my husband would go for one.
Could a 21lb Jack Russell Terrier be toted around on one?
Dave thinks it would be fun to take Cooper along on some rides.
JRTs were bred to ride in bags on fox hunts. They could not keep up with the horses like the beagles but they were brave enough to follow a fox into a tunnel.
Our Agatha loved to ride anything when she was younger. Bikes, tractors, golf carts, motorcycles, backhoes...It came natural for her.
We hope that Cooper will find a bike basket fun.

I need to see if there is a local source.
