Query: Made my dog very, very sick...

Gave this bone to my dog...the next day, he wouldn't eat or drink anything, was lethargic, vomiting. This continued for 3 days til we took him to the vet. $93 & an IV later, the vet says, yep, it was the Jumbone. It completely messed up his digestive system. No more dog treats for our dog!
