It sounds like there are a few things going on with Amigo. The losing fur could be due to fleas, mites, allergies, ringworm, skin infection, or hormone imbalance. The diarrhea could be caused by a sudden change in diet, intestinal worms, GI illness, eating something rotten, or a foreign body. He needs to see a vet for these problems. The vet can diagnose what is causing them, and how best to treat them. I would take him into the vet first thing in the morning. Best of luck, I hope this helps!
