I am so sorry that you've lost your pet Dovy. Whether he passed thru an accident, or you had to put him to sleep, he will always be grateful for the love you gave to him in his lifetime. Our pets know and understand how much we love(d) them.
Many of us here have had after-death experiences with our precious pets. I heard my dachshund running down the hall two different times after he passed. I used to play with him by running in the hall with him! :) My sister felt her very sick kitty who she'd had to put to sleep jump up on her bed at bedtime, walk alongside her, and softly meow by her face. One lady here had a kitty rub against her legs while in the bathroom, and she saw the kitty out the corner of her eyes -- not directly looking straight on.
Talk to your Dovy, tell him how much you loved him, and ask him to come for a visit. I'll just bet it will happen!
May you find peace and comfort in a lovely ADC from Dovy!!
