I lost the best dog I ever had a while ago. I know how you feel. So sorry.
I have a cat, so I still use my dogs auto water feeder. I sit near it on the computer and almost every morning, the bottle will make a glug, glug sound like it did when she was drinking. I will look over and no one is there. Gives me a warm feeling that she is still by my side.
My Kolbe (lab) had a jewel necklace I had made special for him.
I wear it now. : )
His picture is in a 8x10 fancy wedding type frame on the living room table.
