Rex

he is just the most playful, affectionate and semi calmed natured dog. He'll sit patiently for attention and sometimes will fall down onto his back in a relaxed position.
Given he is a very young puppy still he still needs lots of attention and training. Rex listens well and would enjoy quality time training working that smart brain of his. Rex will need a home suitable for his size. Rex would love a home with lots of space to get out all that energy out.
Rex will need a home that can provide lots of exercise, a secure yard and someone experienced with large dog breeds.
