Here's a interesting thought. My dog, who is 5, came from a back yard breeder who basically kept him in a shower stall his entire life up to 4 months of age. I nabbed him because my brothers wife had his sister and she was oh so cute!
His FULL sister, same litter, same mom, looked like a min pin. She was taller than most min's but still 100% looking like a min. Sim comes out like a fat sausage...lol I should of called him Jimmy dean.
This is what my small brown puppy grew up to be:
oh and he's my energizer bunny on crack. When he's not sleeping and lazing around while I do my work, Me and him are hiking 20 miles a week. We went on a 20mile mountain trail and it just about killed us humans....Sim was just a chugging along!
