Dog food depends on it. Some brands are still very cheap. You should be able to accept 5-7 yuan a catty, right?
There are many such brands, and some of them respond well.
I can show you my homemade formula for medium and large dogs.
20% beef, 20% chicken skeleton, 40% rice, 20% carrots, vegetables and fruits. (Change ingredients to play every day)
Nutrition in beef is indispensable for dogs. But the price is not cheap either.
