Im goofy and I know it :) Hi my name is Thumper and I am a very unique puppy that is ready to charm you, love you and be your best friend for life. When I was born the vets in Puerto Rico werent sure but thought I needed a special hernia surgery. After going to the best vet hospital in Mass (Tufts), they doctors determined I have missing vertebrae in my sternum. I have a special lightweight vest I can wear on my adventures to protect my chest area. It doesnt stop there though, I also have very lax tendons and ligaments based off X-Rays, hence my name Thumper, I pound around on my extra big cute paws :)... Its not annoying cause you can truly tell where I am at all times! I am almost 5 months now, fully vetted and neutered. I love other dogs, I can play and run for hours with dogs of all sizes, 4 pounds to 130 pounds. I dont mind cats at all and co-exist with them well. I am a lanky thin boy so eat my meals with vigor. I do eat alone just because I get so excited not because I am aggressive. I am almost fully housetrained, sleep on the beds and couches and like to follow you around like a magnet. I am a great boy with my vest and joint supplements. You would truly be adopting one of a kind, oh and did I mention I have the cutest beard :) Thumper is being fostered in Marshfield Ma.
