What do you do if your dog dies?

[Tobi]

My dog hasn't died, but I found myself waking up this morning wondering what you do in such a situation. I've buried hamsters, buried goldfish and other expired pets, but a dog is a bit bigger. Are you 'allowed' to just bury it in your garden, if you have one? Are 'supposed to' take it to a vet for disposal? Can you compost them? etc etc.
I look forward to some illuminating answers. I think my dog will probably last another 6 yrs or so, so no rush.

Ive never seen one pass away but we've had to put down 2 for medical reasons. They were both cremated and sit in a cabinet.
