Yep, it can be a mess...did he give pup amoxicillin
? Thats seems to work
the best for my Chi's when we go thru the gardia or have intestinal issues..
Then I pull up food, and bowl rice, drain, and give rice water alternated w/mild )not red) gatorade, feed some real quality soft dog food, give "pectin" vet can prescribe, and a little bite of cottage cheese, as soon
as I see a good stool, we start blending the soft w/hard and switch over completely to hard...
