Query: Great carrier!

this bag is comfortable and easy to carry. it provides excellent stability for my active shih-tzu puppy who moves around in it. it's easy to get him into the bag by just picking him up and lowering him into the head opening. i unzip either side of the bag and he crawls out. the tether is great. it gently pulls him back which helps with training. the only disadvantages are that the ventilation isn't super, it's just okay and there is no built-in owner convenience for items such as a wallet or to carry water for you pet. other than that, it's a great carry around bag. i've been in stores and people don't notice it's a pet carrier until they see my dog.
