Handsome black lab for partial adoption

We are looking for someone to co-own a black Labrador named Romeo with us.  Romeo is very handsome, incredibly sweet and affectionate. He is 6, but still thinks he is a puppy.

We have been fostering Romeo since last summer.  He gets along with cats and is AMAZING with children, even babies. Romy sits, lies down, waits on stairs, and has pretty good leash manners for the most part.

We have a baby at home, or we might consider taking Romy full time. We think it will work best to have Romy 50% of the time. Dog food, dog day care and veterinary costs would be split evenly. 

We are committed to having a happy, healthy, well-trained and well-exercised dog.  We look at our dog as a member of the family.

We could do a week on and a week off or some other creative arrangement. We live in Belmont, near Cushing Square.
