Dog Mineral Feeder?

I have heard many success stories about giving cows/sheep/pigs minerals for health benefits but I haven’t heard much about giving minerals to dogs. Has anyone tried it, and what minerals do you use?
We have a pet dog (not a livestock dog) and want to make sure she has a long healthy life.

I feed my dog raw, and took a certification course, too learn the best way. This - is what Iadd, as a supplement, in case it feels like I'm missing something, or can't get something, normally in what I make,  etc. It helps me make sure my bases are all covered. I get nothing for sharing this, and this isn't even where I get mine(I use a subscription type thing): https://www.chewy.com/rx-vitamins-rx-essentials-powder/dp/186063?utm_id=401602724&msclkid=534b310848081aa2d2e952d77abeaf47

I feed our dogs kelp in their food. Kelp is a complete wholefood mineral source. I make sure it is sourced from places like Norway, one of the fewer parts of the planet with still relatively clean ocean. I don't like to give any mineral isolates since humans don't know enough about the correct amounts and balance of minerals any of us need, nor do we understand enough about how they all interact with one another, which is why I keep all supplements in wholefood form.
We have had many dogs over the years. Not one has ever had any type of tumors or cancer, none has had any allergies, nor anything else, for that matter. Their teeth are healthy and don't require brushing. The only time they go to the vet is when it is time for the rabies booster, which in our state is required every 3 years. Every single one of our dogs has lived long, healthy lives, and our current two dogs seem to be following the same trend, with our older 90 lb. male at almost 10 years old now still running to retrieve a stick or ball as if he was 3.  We also do other things differently than what many do as far as what foods we feed, vaccination protocol, etc.

Thanks for the advice!

Can I have yalls raw food recipes? I've been looking into raw feeding but I just can't seem to find non-*insert mainstream dog food company here* sources. Thanks!

This is loosely based on Dr.Judy Morgan, DVM's 'Pup Loaf'

Raw 'loaf' formula:
8 # grass-fed raw beef &/or red game meat(venison, elk, Bison, etc - sometimes with poultry, rarely with pork),
1# raw organ meat (kidney, brains, glands, etc)
3/4 - 1# sardines, mackerel, or salmon
1/2# liver
1/2C raw, dried, ground eggshells from above chickens
1C psyllium husk fiber (or oat bran, if the psyllium husk fiber is unavailable)
1/2C mushroom powder (Shirakawa, reishi, lions mane...)
1C flax seed
2 heads garlic
12oz fresh or frozen blueberries
12 oz fresh or frozen cranberries
1 -2# kale, broccoli, cauliflower, etc
1/4# fresh ginger
1# celery
1# carrots
1bunch parsley
1# pumpkin
1/2# bananas
2T cinnamon

Gently cook veggies, until tender, cool. Combine everything well, portion, and freeze, for simple, wet food. But, for several reasons, I dehydrate and portion @ 24g/meal, for my little cavalier. This way, it's also shelf stable & convenient, travels well, etc.
