Hi Amberstone --
I have a dog share! My 70 year old neighbour's daughter has 3 yorkies. The male inpreganted the two females within days of each other -- so there were 11 puppies (that survived). Anyway, Susan gave any of her family members a puppy that wanted one, and sold the others (keeping one for herself and fixing the male).
My neighbour wanted a puppy, her husband said, "No." They have two cats, a perfect garden (they spend all of their time in there working away), and like to bus trips with other retirees.
So, she comes to my house Monday through Friday at about 10 am and takes my dog for a walk. She keeps it when we are away, buys it littel gifts, feed it snacks, etc.
I "support" the dog. She sleeps at our house, etc. But, we are all pretty certan she'd rather be next door with "grandma" who spoils her. lol
It works well. You might see if there is someone in you rneighbourhood who likes to walk for fitness but can't have a dog because of a lease or expense or whatever reason.
BTW Yorkies do not shed, are very smart and housebreak easily, and if you get a bigger (not shown quality) one -- pretty healthy.
