We're dog sitting my in-laws tea cup chihuahua while they are on vacation. It may weight 6 or 7 lbs. It was sitting next to me on the recliner half wrapped in a blanket and my cat climbs up and literally sits on it like it wasn't there. The cat weighs 20+, so there was basically no part of the dog visible. Thing thing never shuts up when we visit them, but my puppy wont leave it alone and I think it's in a perpetual state of shock.
