The only animals allowed on the greyhound bus is service animals.
No better answer than the one of shamel.
Your allowed one bag that can go under the bus an one carry on per adult. I believe the bag can be no heavier thank 50lbs. If it's over the required weight and any additional bags you will have to too pay extra. I'm not too sure about the dog but if they allow it he may have to be in a little cage or doggy bag
