I just had puppies one week ago and noticed the runt is having a bright yellow stool, is this normal? He also dragged it along the other puppies

This can be an indication of irritation or infection of the GI tract. I'd have him checked out by a vet. Be sure to bring his mother and siblings with him to the appointment since he cannot be separated from his mother.

    Color changes in stools can happen with changes in diet or several internal things. Sometimes, yellow can indicate an issue with the liver or intestinal parasites. I would recommend having Milo examined by a vet to see what could be going on.

    Yellow/tan colored stools are very abnormal. This is generally an issue with the liver. It could be the sign of a sign of liver or biliary disease or it could simply mean that your dog’s poop moved too fast through the GI tract to pick up the bile which changes the color to the normal brown you recognize. I suggest you start a probiotic (one made for dogs) to give for a few weeks and also have a fecal test done by your vet to rule out internal parasites (worms).

    It may just be due to something he ate if it's only been once or twice. But, some parasites such as coccidia or giardia may cause yellowed runny stool. I would recommend having a veterinarian check a stool sample for parasites if they are having multiple runny stools.
