It is much cheaper to feed DIY raw. How much are you paying per pound for your food? Depending on what I feed, i pay .50/lb to $1.50/lb. I get a great price for rabbit, venison, llama, goat, sheep, beef, tripe, chicken, pork, etc.
I don't spend much time preparing meals. I am feeding 4 dogs. One dog (Madina) has allergies to most things and gets fat very easily, so I have to spend more time preparing her meals. For her, we still weigh and bag the meals every other week.
When I was first starting out, every week or so my hubby and I would bag up meals and weigh them, with the right amount of bone, organ, and muscle meat. It took an hour or two I'd guess. After a while we got the hang of it, and now we just thaw out food as we go. I have boxes that are probably about 20-30 lbs, with the right amount of organ/meat/bone, and we distribute it to each dog, just eyeballing ratios and amounts. It just takes a few minutes to put the right amount in the bowl for each dog.
