I am still pretty heavy on some of it. I took large deer in 2005,06, and 07. At the same time, a lot of my friends that used to take venison moved away. A 70 lb doe is easy to finish off. A 270lb buck takes some serious eating, and there is only 3 of us in the house during the week. We've been known to fix venison 3 meals a day, 3 days in a row in the winter. It still piles up.
I make dog food from whatever passes the point of no return. I get a big pot and put in enough water to cover what I'm going to make, and then go about cutting up everything into small chunks as the water heats. Every pound or so gets tossed in the pot. When I'm all done adding meat, I wait until the water boils and then let it simmer for an hour. I also boil all the bones to get whatever good is left on them, and then put them aside.
After cooking for an hour or so, I let things cool off slowly and set about cleaning off the bones. Bones go in the fireplace, meat goes in the pot. When it's cool enough to handle, I remove all the meat and drain it. The broth that's left gets measured. Based on the amount of broth, I cook measure of rice. After the rice is cooked, I mix meat and rice, measure into sandwich bags and freeze. The dogs get about 5-6 ounces apiece to go with their kibble every night.
My beagle loved it so much that the first night she got it, she ate her dinner and then came and jumped on the bed, woke me up and gave me an outpouring of love such as I've never seen. Someone else had fed the dogs that night, but she remembered my labors from the previous morning; she knew who had done the cooking.
I cook a big batch of dog food in the dead of winter when we're snowed in, a big batch in the summer when it's too hot to go out, and a batch now and again when bad weather keeps us indoors.
