Ajax has yet to accept his age or size. This almost 8 year old dog acts like a pup. He loves to run in the yard and play. He does take more pet breaks than he used to. The will let you pet him all day long if that is what you felt like doing. He is a sweet boy who needs someone with patience and time to get him trained. Unfortunately he wasnt given the best life so far and needs someone to show him how to be a good house dog.
