DIY Frozen Tuna.

What you need:

• An ice cube tray.
• Can of water-packed tuna (alternately, you can use canned salmon).
• Approximately 1/2c water.
• A mixing bowl or magic bullet.
• A Ziploc Bag

Step by Step:

1. Start by mashing up the tuna in your bowl. You can also use a mixer. Don't drain the tuna water, it will help to freeze. Add a half cup of water to the mix.
   
2. Then mix up the tuna. You can use a beater.
   
3. Fill the Ziploc bag with the mix and cut a small hole in one end. Fill the mix in the trays and put in the freezer. You can let your dog lick the bowl.
   
4. When the treats are frozen, push them out and serve them on a plate. Then let your dog enjoy! You can conserve this in the fridge for 6 months.
