We bought this to travel with our puppy but we chose to get a big cage for him for the plane because he has too much energy for a long flight. This backpack is nice and large and fits a Jack Russel. It will be very comfortable in city buses, cafes, supermarkets or camping with your dog or cat. It's also good for older dogs who have trouble walking long.
Text me any time. We can meet in the Agios Nikolaos church parking lot.
