@Ron816 maybe you could put up a poster with a picture and a memorial message. I can only image how challenging being constantly reminded by unknowing customers will be. I honestly don't know how I could do it.
I am very sorry for your loss Ron. I lost my little best friend, Prissy, on July 21st. She was 17 and was with me for 16 years. It is terribly hard to let them go, even when it is the right thing to do. I think that memorial idea is great. Maybe even print out a copy of The Rainbow Bridge poem to put with it.
MAN, SO sorry about Y'alls Loss. DAISY LOOKS LIKE A COOL DOG! Princess Passed Away the day before Valentines day, in 2020, right after we moved in here. Bad Omen for the house...tell Daisy to Bark "Hi!" To Princess, so they can hop in a Mopar and get a ride together! Sorry Again, for the Loss Of aoved One. Gotta run, sprung a leak...
