The little corgi's stool is jelly-shaped, perhaps for the following reasons: First, its gut flora may be out of balance. This can be due to an irregular diet, poor eating habits, or excessive intake of meat and greasy foods. In this case, the feces of the little corgi may become sticky and appear jelly-like. 
In addition, the little corgi may be infected with viruses such as parvovirus and canine distemper. These viruses can invade its intestines, causing the feces to appear jelly-shaped. In addition, certain bacterial infections, such as E. coli and Salmonella, may cause similar symptoms. 
Also, if the intestinal parasitic infection of the little corgi is severe, such as coccidiosia, Giardia, etc., it may also cause its feces to be jelly-shaped. These parasites can multiply in the intestines, causing inflammation and intestinal damage, which can affect the shape and texture of the stool. 
If the little corgi suffers from chronic diarrhea, indigestion and other diseases for a long time, it may also cause its feces to be jelly-shaped. These diseases can affect its digestive function, worsening its gut health. 
In short, if you find that the feces of the little corgi are jelly-shaped, you should take it to the veterinarian in time so that the diagnosis can be confirmed and corresponding measures can be taken. At the same time, we should also pay attention to adjusting the diet of the little corgi to maintain its intestinal flora balance and prevent risk factors such as viral infections and bacterial infections.
