It's an interesting diet this breed needs. Basically small frozen scraps, but very rich in content. Their digestive systems evolved as nomads north of the Arctic Circle and know nothing else, so a bit of care needs to be taken. His body will do a lot with the vital scraps of tundra animals, and doesn't know how to handle big foreign diets which make him unenergetic and unwell after a few meals.
Tonight's menu is sheep and beef tripe—their organs go well, but their meat and fat doesn't.
Frozen salmon cuts—these dogs know fish as well as reindeer and love frozen meet. They extract all the goods from them.
And a rabbit foot—Fur and bone is common in their diet and helps clean. They can start to poop bad without fur fibre.
One of the more tame dishes considering the other weird off cuts of bits and pieces he gets. Thought some may find it interesting for a bit of an unusual breed outside of Finland.
Edit: And yeah, the photo makes the meal look big and him small. But he's 20kg and that dish is about 3/4 a banana in diameter.
Good grade dogfood is nothing like burgers and ice cream though. There's not enough information of the diet OP uses so no comment on that, but it is easier to make dogs sick by feeding them only pure meat than with just kibble. Obviously don't buy the cheapest processed shitty dog food, but please also do consult a vet and do some research before trying to feed a raw diet as well. Wetfoods and kibble tend to have the vitamins and fibers and all that added, but feeding a raw those need to be considered more.
And lapphunds 100% don't need fancy meats any more than other breeds - nekin on tosiaan vaan koiria eikä mitään ihmeen taikaolentoja.
