My 1 month puppy having loose stools. What could be the possible reasons for this, and are there any remedies I can try?

Hi Pavithra. Since your pet is just 1 month old, there can be chances of having him/her infected with Parvovirus or it can be due to change in food or gastritis. You can try giving Digyton syrup for now but I would highly recommend you to speak to a vet either online or by booking a home consultation on kuddle.
