Eagle Crest

on 7/26/11 at approximately 3 pm my 11 yr old son was walking our American Bulldog/Great Dane puppy in the back yard when he pulled and snapped his collar.  We searched for over an hour.  He was last seen in the area of 6th ave n and 61st street.  His name is Piper, he is microchipped, white with black patches.  very friendly.  and way too curious for his own good.  If someone has seen him, or knows his where abouts please get word out to have him scanned so that he may be returned.  Thank you.
