We had to put our dear, old greyhound, Porche down last Sat, after well over 15 yrs of being a very happy dog. Always happy to go off for a ride in the forest with the horses.  I was judging that morning, so my husband and older daughter took her to the vet ( aside from old age, she had been suffering from liver cancer for 2 yrs, and her metabolism was not working well. She was acutely thin!).  When I came home,  it was my job to take Porche down below the arena, and bury her next to her…
