The second question, three months 1 1 kg, is a little thinner, it should be more than 15 kg.
The third problem is that Samoyed can't feed all the homemade dog food for three months. It will take at least five months to use all the homemade dog food.
Your dog's low weight is the reason why homemade dog food or dog food used to be wrong.
3-5 months should be based on puppy food, and A2 (long meat) is recommended. With avocado (beautiful hair) Formo (strong bones) Ames (comprehensive nutrition). You can add your homemade porridge appropriately.
It should be fed with dog food for more than 5 months, because dog food contains special nutrients that dogs need, and some vegetables and foods are not easy to absorb directly. You can use the materials you said, but don't cook porridge, make it into a nest. There is not enough porridge. Eggs only add egg yolk, not egg white, not digested. Carrots should be oiled first, but the oil is not nutritious.
You can use corn flour+millet flour (rich in nutrition)+oats (a small amount of crude fiber)+whole wheat (a small amount)+chopped carrots that have been oiled+chopped vegetables (Chinese cabbage, cabbage, spinach, celery, etc.)+meat (chicken, duck, beef) or liver (you can only eat about 50G a week, that is, three chicken livers or a small piece of pig livers)+. You can add a little chicken essence. Steam in the pan.
You can also use (rice+millet) instead of (corn flour+millet flour+oats+whole wheat) to cook porridge and mix with dog food. Rice and millet must cook porridge, which is not only nutritious, but also easy to digest. Steamed rice is not easy to digest.
Our family gives a stick bone a week, that is, the thigh bone or dragon chops of pigs, that is, the spine of pigs. When cooking soup, don't give it to the dog, but give it to the dog. You can chew it as a molar bone for three days.
