I like this little clip I captured this morning, it's what Doggie Daycare is all about (the dogs playing hard and having fun). It's Bella the little white Boxer (She takes on all comers!) fending off Osbourne the Chocolate Lab and Benny the Golden Retriever, all in good fun of course.
-Grant P.S. Also found many dog articles of interest this morning (click the numbers)... 1, 2, 3, 4.
