I have started giving mine salmon oil recently, they have been on it for a couple of weeks now and have been doing great on it.
You use it daily and it comes with a pump that you just pump onto their food. They love the taste and smell.
Here are some benefits of the salmon oil:
• Cardiovascular Health
• Support of Brain Function
• Improved Immunity Against Infection
• Beautiful & Lustrous Sheen to Coats
• Improvement in Inflammatory Conditions
• Increased Bone Strength
• Improved Growth & Development
• Improvement of Dandruff & Dry, Patchy Skin
• Readily Available EFA’S
• Increased Joint Mobility
• Lowering of Cholesterol
