16 wk old has loose poop everytime after he eats. He's on Natural Balance sweet potatoe and fish. Sometimes it can be very smelly and w/mucous. This has been going on for about a week now.
He has already been tested for worms and he was negative. I've never had a problem with the rest of my yorkies and they are all on NB.
Have already done the rice and broth for few days and he's fine but once I give him a little of the dry food he starts again w loose poop.
Any advice truly appreciated - I'm starting to worry
