Dog Questions

So we are planning on taking a little toy poodle puppy with us on an airplane. Not on the way there, but on the way back. Does anyone know like good brands of Kennels or Carriers to buy for a dog to be carried on to the airplane? I know it can’t be more than 10 and a half inches high and stuff… but is there anyone that has ridden with their pet in an airplane and knows what kind of carrier can be approved? I don’t want to get there and have them tell me that the carrier isn’t leak proof or something. Thanks a ton!
