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.
