Things to Consider When Choosing the Best Fish Oil Supplements for Dogs:
Source
Look for supplements containing EPA and DHA, which are the most beneficial types of Omega-3s for dogs. These can be derived from fish oil or algae oil. Look for products that source their ingredients through wild-caught and sustainable practices.
Purity
Choose a product tested for purity and contaminants, such as heavy metals or pesticides. Any brand that doesn’t provide test results may not be the right one for your dog. Also, look for natural and organic labeling to get the cleanest and safest product.
Dosage
Be sure to follow the recommended dosage for your dog’s size and needs. Products should list dosages per weight, but the Colorado State University James L. Voss Veterinary Teaching Hospital offers this Canine Fish Oil Dosing Chart for reference.
Form
Omega-3 supplements for dogs can be found in capsules, liquids, or chewable tablets. For some, giving their pup a soft chew or a gel capsule is the easiest way to dose their dog and can help reduce the fishy breath that sometimes comes with fish oil. But the ultimate ease is pumping fish oil liquid over their dinner. Liquid forms can also help ensure your pup receives the full dose, as sometimes capsules may not fully melt for optimal absorption. Really, all forms work great for dosing your dog with beneficial fish oil. It’s up to you to decide which delivery method works best for your pup.
