Did you know?
The most popular green grape variety worldwide is Thompson Seedless — also called Sultana in Australia and the UK. Thompson Seedless grapes are the same variety used to make golden raisins. They were developed in the 1870s by William Thompson a Scottish-born viticulturist in California. The seedless characteristic makes them convenient but provides no safety benefit for dogs — Thompson Seedless grapes cause the same kidney failure as all other varieties.

What You Need to Know
Green grapes are not safer than red or purple grapes. This misconception sometimes leads owners to believe seedless green grapes like Thompson Seedless are safe — they are not. All varieties have been implicated in kidney failure in dogs. The myth of safe grape varieties may have originated from dogs that ate grapes without apparent symptoms — some dogs appear more sensitive than others but no variety has been proven safe.
