I am so sorry about your dog.
My hamster Pashmina also had a horibble death.My ex threw her across the room.She hit a wall and bled to death.I created Pashmeena in loving memory of her.Cubby and GooberWoober are also named sfter hamsters that I had.
I really don't know what I would do if something ever happend to Hamtaro my current hamster.He is everything to me.We do everything together.I also take him everywhere.He just turned 2 on Christmas.He is getting old,but he still acts like a baby.
