I’ve been raw feeding for six years now and can attest to the great health benefits I’ve seen in all my pets. My pitbull has bad allergies and she’s now the picture of health. We rescued a sickly old mastiff off the side of the road and he’s blossomed as well. My cats are all strictly meat only (bone-in chicken thighs, hearts, liver all ran through the grinder with a couple supplements) but I do add about 10% non-starchy vegetables to the dogs diets. Dandelion greens (plus a root or two), zucchini/squash, pumpkin, kale, blueberries, wheatgrass, broccoli, carrot, etc. with a dollop or two of sauerkraut, I pulverize everything in a food processor and freeze it in ice cube trays enough for a months worth. They don’t have the correct enzymes to break down vegetable matter very well since they usually would only be eating the pre-digested contents of their prey, pulverizing it down into a pulp allows them to extract the nutrients much easier. Their meat and bone I mostly source through a raw feeding co-op for a good price but does require a dedicated chest freezer to store. Beef heart, pork chunks, duck necks and heads, whole sardines, duck eggs, lamb liver, beef kidney, sweetbreads, and pork spleen. If you could get up with a game processor or small local farmer others have had great success getting all the offal and off cuts for cheap (don’t be afraid of some fatty bits), large bones are great treats or chop them down and stew for a couple days for a great bone broth. It’s vital to remember the importance of ratios, approximately 10% of their diet needs to be edible bone (whole poultry or carcass, bone in fish, feet) and another 10% is offal (5% liver then the other 5% another organ such as kidney, spleen, sweetbreads, testes, etc.) Do note that hearts, lungs, and tripe aren’t considered an excreting organ and should be considered as meat portion.
Mind you, I do spend a couple hours every couple weeks to pre-portion their meals into takeaway containers that go in the deep freeze so I can grab a few to thaw in the fridge and feed without having to prep every time. My crew are my beloved pets and I understand LGDs may not be deemed worth the effort to prepare everything like that, but having a few bags of frozen liver, sardines, carcasses, heads, etc to toss them to make sure they’re getting approximately the correct nutrients wouldn’t take much effort or cost. I’ve started researching about raising our own animals for feed, seems that rabbit, guinea pig, quail, and goat would be the easiest and most economical. All except goat could be fed whole so processing would be very easy and all their ratios would be met. Not to mention if you took the time to dress them out a nice protein variation for your own family.
