I'm sorry to hear that he's sick but I'm so glad to hear that he's already much better. I was told that both Alani & Blaze and their other two siblings all had giardia when they were brought to the rescue group. They were found near the coast with their mother and they were all strays. They said the water was bad there so this most likely caused the giardia. Unfortunately no one was able to catch their mother or one of their siblings so they're still out there some where.
