She uses a small ice cube tray that measures about 1 tablespoon per cube. She puts the tray in the refrigerator where it sets up nicely. She gives each of them one of the cubes per day and the change in their skin and fur has been absolutely amazing. They really seem to enjoy them and consider them a treat. Ours are both around the 10 pound mark (Chinese Crested) and she was instructed to give 1 tablespoon per 10 pounds of dog, but you should/could talk to your vet if you want to make sure on the amount. I'm a huge fan considering how much it's helped them in the past 6 months.
