Puppywalk SUV Pet Stroller/Carrier for Dogs and Cats: The Puppywalk SUV dog stroller is 30% larger than the original. It too is a pet carrier on wheels!  It's ideal for trips to the vet, or safe walks in the park - or go off-road with any pet up to 50 lbs.   The padded carrier has two compartments: open air netting and a fabric enclosed privacy parlor. The carrier detaches from the stroller and can be used by itself  - and the stroller can also be used separately as a wagon for easy hauling of groceries, etc.
