Liz Conmy's students at Minnesota State University sold about 500 jars of pickles.
Her family makes them and had plenty left over.
So, her public relations students came up with the idea to sell pickles, to benefit Great Plains Assistance Dogs.
The students surprised trainer Sharon Raugutte with a check for more than $2,000.
She says the money will help put a new roof on the kennel and buy office equipment.
