What did you do with the dead pets?

All of my dogs or cats, were either buried in our backyard or at our camp in the country. I always felt I owed it to them to have a nice place to rest. We put up little headstones and planted flowers of bushes at the head of their graves.
Even that big snake got a proper plot in a wooded area. Some people let the vet take their dogs and cats to be buried or cremated, or both. Not sure what they do with them, not sure I want to know.
