Hi, sorry to hear Rex is having diarrhea. The most common reasons for puppies to get diarrhea is worms. make sure he is dewormed properly by a vet. bring a stool sample to have them test it for worms, because not all worms can be seen without a microscope. Another reason is diet change. Since he is a puppy, it is likely you changed his food since getting him or have given him a treat he is not used to. And puppies are mischievous and can get into things like people food and garbage when not supervised. I would start by feeding hm a diet of boiled chicken and rice instead of dog food for 2 days to see if that clears it up. If not, take a stool sample to your vet and have him looked at and dewormed. Good luck, I hope this helps!
