My 2 years old shihtzu dog has suddenly started pooping like this since yesterday. There is no sudden change in his diet and was well till day before yesterday. What could be the reason ? What measures should i take? Please help.

Hi Piyush. If there was no change in diet it could be due to worms or an infection(bacterial/fungal/coccidial). Deworm him if he is due. Try to incorporate curd in his diet. I would suggest you to speak to any vet online on kuddle to discuss more on this and for the diagnosis and treatment. Stool examination is recommended as well.
