My daughter, who has lost 2 dogs, a boxer and a dalmation, has had both cremated. She has them in urns and has buried them in the yard. When she buried the urns she made plaques with their names and ID tags out of a kit she found at the craft store (it looks like a garden stone). She has moved several times since they have passed. Now when she moves she just packs them up, takes them with her, selects a place and moves them to their new home.
I'm so sorry for your loss. They are such a part of the family.
ps I want to be cremated also. If Bubba and Sissy pass before I do I want them cremated and placed with me. Then I want us scattered as I love to wander. Sorry I hope this doesn't sound morbid as we are not planning on going anywhere for quite a while
