Just a quick note on feeding from an old dog musher..
I have the past two years been feeding my dogs more with fish and raw meat. I freeze the fish for them , making their teeth nice and clean chewing the frozen fish. Meat I give them bones from the slaughter, and other cutoffs I water out to a soup so they get about 3 litres of water a day when running, and 2 when not.
I used to feed them mostly high value pellets before, and they was healty then, but we have had no visits to the vet since two years, they pull harder longer and they got more shine in their coat.
I have worried a bit about shortage of vitamins and so, but as I see it they get a hunger for what they need if anything and start chewing grass. As long as they look fresher than ever I'll keep them on raw food.
Note my dogs are sturdy alaska huskies, small pet dogs might not take this amount of fat as well.
