We just lost our beloved bear yesturday at the age of 10 and I have another dog who I 've had for 13 years he was the pack leader and he seems to be taking it pretty good for now he saw his brother die and gave him some licks but I was wondering does he really realise that he's gone he saw him pass away .we're still trying to get over the loss they have been together since pups .don't know what to do or to expect
