We took in an elderly GSD who 3years later required massive surgery. The vet sent us home with ABs and Rimadyl. On her first day of meds, my SO gave her the doses, and then put them on the coffee table (it was a struggle getting them into her, so he was absent-minded about sitting them down and forgot to put them up). I came home from lunch to see one of my pugs vomitting. When I realized he had eaten 25 GSD sized Rimadyl, I grabbed the bottle of Sonne's #7 bentonite clay, gave him about a tablespoon, and rushed him to the vet. They put him on IVs and monitored him with blood tests, waiting for his liver to crash. Between the pug vomitting up a good portion of it and the bentonite clay pulling it back out of his system, we were fortunately able to avoid the liver crashing. The vet is still scratching his head, though - he doesn't really understand the bentonite and how it works.
