I'm now a foster mom! To a puppy

My stepsister is Executive Director of One of a Kind Pets in Akron, a no-kill animal shelter. She's overrun with dogs and puppies right now so I'm fostering a cute little boxer-mix puppy about 8 weeks old. Of course, my Bo and Sasha are beside themselves but are being good hosts, provided that puppy keeps off their bones! We're only keeping him a week...I swear we are not KEEPING him forever...I've already had the "talk" with the family.
