Some of the stools formed are quite normal.
Some of them are soft, so they are generally related to what they eat. They contain a lot of water, or some of them are not well digested, but this is not a problem. Just adjust your diet.
If the diarrhea is very thin, the gastrointestinal tract is not very good. It is necessary to observe whether it is simple indigestion, cold diarrhea or other problems.
Extended data:
Please don't fall into the mistake of feeding dogs a single diet, even if you provide them with the best quality diet, because dogs are not defined as hunting animals and scavengers in nature, and their diet has always been very extensive. Besides, dogs may dislike eating the same food every day even more than humans. At the same time, there is not enough scientific research to prove that a single diet is balanced and comprehensive for most dogs. Maybe a single diet is not a healthy feeding way for dogs. Some allergy researchers believe that dogs can avoid food allergies if they are fed various foods from infancy.
