The location and depth of soil you choose will determine your dog’s postmortem fate (or your gerbil’s, or ferret’s, or turtle’s). Do you want him to become part of the garden? If so, bury him close to the surface or in rich soil, where he has the best chance of decomposing fast and completely. If you want him to stay around longer, wrap him in plastic and place him in a sealed box, buried deep down in the soil. Although if you really want Growler to stick around for the long haul, may I recommend taxidermy?
