Hi, @Mom of Tucker This pup may have a bad case of worms,coccidiosis, giardia,or it could be the food. My Frenchie was being fed pr plan when I got her, and I kept
seeing blood in her stools. Started giving her grain free, and she was fine. Of course that pup has definitely got to see the vet. If he was given shots bought at the local
feed store-they are not much good. When I worked for vet years ago, many dogs came in with Parvo,whom the owner said they gave them their shots,which they got at
the Co op.
