I don't think it's a lazy dog. I met a Spaniard from Galicia who walked with a small dog similar to this one his name was Goron ( the dog ) I believe his master was a tennis instructor . The dog suffered especially walk on ashfault but okay on regular ground. so I understand this dog being in a stroller . Just remember the dog's master was called Jordie..very nice guy this was on the Camino Norte.
