Boomer has always loved being with other dogs...but the feeling is not always mutual! My Mom's Yorkie always try to bite him when he comes over (but my Mom's dog is a horrible little dog )...and my brother's Border Collie was hesitant at first, but she came around. Boomer won her over...who could resist a crazy boxer leaping about and sticking his butt in the air? My ex husband's dogs love to play with Boomer, and my sister's chocolate lab is his best buddy.
