I'm looking for recommendations on backpack style pet carriers. I want to buy one by summer so I can take my dog bike riding with me. I do not like the front style carriers, pouch types, or the ones where the legs hang out. Airline approved would be a plus. My yorkie is a big one at 15" long 11" tall and 10lbs. Thank you in advance for all your help.
