He would be and honestly, I could have had him with me. But I decided that it would be best to go the pet route for him in this phase of his training. The flight was quite long and I don't think he was quite ready to behave and lay down for the 3+ hours... I just didn't want him to be "one of those service dogs" you know?
He's young, and we've taken longer car rides together but that's with stretching his legs and a bit more space so yea, YES THEY CAN, I just decided not to because of his training status
