Bowzer's Birthday Cake Recipe

From The Good Food Cookbook for Dogs:

1 lb. of cooked ground turkey or chicken (ground steak - no fat)
2 carrots diced
1 cup of cooked brown rice
1 ten oz. package of frozen spinach, thawed & squeezed dry
1 tablespoon of vegetable oil (we use extra light olive oil per Mary's suggestion)
1 egg slightly beaten
2 hard cooked eggs sliced 

Place turkey, carrots, spinach, brown rice, oil and raw egg in large bowl
Put half the mixture in a greased and wax paper lined 9 inch cake pan
Layer hard cooked eggs over mixture, then top with the remaining mixture
Bake in 350 degree oven for 45-50 minutes or until done

Remove from oven, let rest for 5 minutes, then using a large spatula remove from pan.  Drain off any grease and let stand 15 minutes before frosting ..with mash potatoes ..or just a few dollops on top ..
you can also double the recipe, make 2 whole 9 inch pans and use mash potatoes in the middle
