Tuna is a very lean protein that is chock full of vitamins and minerals. It’s a good source of B3, B6 and B12, folic acid, selenium, and omega-3 fatty acids. Omega-3 fatty acids are particularly beneficial to your dog, because they support joint mobility, improve the skin and coat, and promote heart and kidney health.
Please note that tuna is only healthy for your dog if it has been cooked. (No doggie sushi!) Never, never feed your dog raw tuna. Certain types of raw fish, including tuna and salmon, can contain a parasite that causes a potentially fatal disease in dogs known as “salmon poisoning.” For your faithful friend, always stick to thoroughly cooked tuna steaks or canned tuna. When it comes to canned tuna, you should opt for light tuna rather than albacore, because light tuna contains a lower level of mercury. And to keep the fat content to a minimum, be sure to choose tuna packed in water rather than oil.
One additional warning: every dog that has tried these treats has gone completely CRAZY over them! Be prepared for lots of whining and begging for more–even from the most finicky eaters.
