Our dog really doesn't like going in the buggy, but it's actually the best way to keep him walking along instead of endlessly sniffing and truffling for tidbits to eat. We just ask him if he wants to get in the buggy and he start motoring. He'll last for a little while in there before he starts crying to get out, unless he's really cold or hurt. A backpack would be awesome, but it'd be like trying to stuff a squirrel in your pants.
