sorry to hear about your loss, Kevin...it is always so painful to lose a member of the family...and yes the others will always know...we have a basset hound that for the longest time would never want to go bye bye in the car....because we took a friend of hers (basically an adopted sister, a dachsund, they adopted each other) to the vet and never brought her back...

The basset now will go in the car happily....but it was alot of work bringing her to that point.
