Acai berries and the juice should be added to this list of "toxins" as it has more than twice the amount of Theobromine as chocolate! I found out the hard way when it caused acute renal failure in my dog very shortly after I added some to his food. He survived, but the symptoms were so intense and sudden, I was terrified! I am not seeing it on any lists as of yet, so I am letting all dog-related sites know. Please add to list.
