I knew grapes and raisins were very toxic, but I didn't know that such a small amount can kill. We called the vet to check if a small amount was OK, next thing they were finding us an emergency vet close to where we were staying. Awesome service and while 24/7 vet costs are pretty expensive, you can easily see that it costs money to have things on standby.
Today we just have black poos to deal with.. So at least the charcoal is working.
