Have just lost Goof, my 13 year old Aussum Shepherd.

Yes cremation is the answer. All my dogs have been. My vet has an apple orchard where he volunteers to spread the remains. I have opted for that every time. They would all have loved walking through the orchard. But at any rate, you can keep him with you till you decide if you wish to do something else with his ashes. My condolences on your loss and may God bless you in your journey to better health.
