Since its relevant to anxieties over supply chains etc I'll chime in with this re: dog food and making your own to supplement or cover for shortages -
1. Anyone making the argument that dogs are carnivores because wolves are strict carnivores is retarded. Wolves are primarily carnivorous but absolutely do supplement their diet with shrubs and veggies if they are available. Also dogs are separated by wolves by enough to shrink them down to fucking purse size, does anyone really believe nutritional needs wouldn't change in that time?
2. Not all dog diets should be the same. Try to tailor your dogs meals to what they're doing and what they are. Slight PLing but I have two different breeds of dogs. My large "sled dog" prefers to get carrots, apples, red meat and chicken, long grain rice and bananas when I can get them. Lots of protein and high energy foods because he runs and is active a lot. My rat dog is much more sedentary and prefers just laying around, and has GI problems when he eats certain things. So he mostly gets chicken, rice, beans, peas and apples. And these are things dogs will love to eat, you just have to break them from eating kibble all the time. A lot of people give their dogs fish and tbh I've thought about giving the sled dog go some trout but Im weird about fish bones I don't want to risk them choking on one. Turkey is a seasonal treat for them that they love as well but remember to cook your dogs their own poultry without using salt or herbs. OH and if you can find them cheap in the store, plain boiled eggs can be a good treat for them but don't do it too often because cholesterol etc.
Most commercial kibble is actually horrible for use as the only source of food for dogs. It's loaded with corn and empty calories and fats and not near enough proteins or other vitamins and minerals.
The problem is that dogs who are raised on kibble will sometimes refuse anything else because to them if tastes great and is fattening. If you had a choice between eating your favorite pizza every day for life or eating new things in a balanced diet, and your brain was the size of a walnut, you might make the same type of choice. It doesn't take that long either and once they get accustomed to it they will want the veggies too. My rat dog actually picks out the green beans more than the chicken sometimes.
3. How this ties into global supply issues? Well, it presents a problem for a lot of people because they don't have the option to supplement store bought food. I strongly recommend researching some dog safe fruits and veggies and starting your own mini gardens. For meat you do have to be careful about hunting or trapping for it too, ALWAYS cook it like you would for a human, it sounds dumb but a house dog is going to be just as vulnerable to intestinal parasites and diseases as you would be when eating game.
4. Make use of coconut oil and pumpkin and stock up on it. Dogs can eat both of them in pure form and it will help with digestion, worms, stomach upset and constipation in place of medications. You can bake or cook pumpkin and I think they can even eat the seeds if you cook them soft enough and its good nutritionally as well.
