More: Gus aka Gus Gus is a man of a big personality. He will come running to you like a stampede of horses only to just jump up for some hugs. This big boy weighs in at a whopping 100 lbs and is still filling out. Gus lives his best life going almost everywhere with his humans. We hike mountains in New Hampshire, visit the beaches of Cape Cod and everywhere in between. Gus is most happy with muddy paws.
