My stroller came in very handy when i went away to Cape Cod with Minnie and Tootsie ( before i got Peyton). we did alot of walking that would of been way too much for them and when they were tired , they could cuddle up and go to sleep. when we were eating we found some open air resteraunts that allowed us to take the dogs , we kept them in the stroller . was much easier.
but if i only had one dog that didnt weigh alot, maybe just a carrier would be good.
