When Ruben raced in the house he went nuts! He went crazy when he saw our 2 cats. After about 15 minutes of trying 2 calm him down he finally settled down. He was just so much fun!!! I was so excited 2 have another dog in the house. We soon learned that he was crate trained,house trained, and knew sit and lay down. When he got into the blanket closet he pulled out 2 old sleeping bags and even today he still sleeps with them. He was so much fun 2 walk,play fetch with, and just hang around.
