So sorry to hear. Chief, my Black Lab, just turned 9 yesterday. Had him since he was weaned. I (nearly) joke that he's more loved than I am. He's starting to get gray around his mouth and face and takes much longer to get up now days...wow...so different from the Pup who was yelping in my Bronco as we drove away from the breeder. But, time keeps moving on and on... Sorry for your loss.
