 "I started adding this to my dogs' food because one of them was struggling with dry and itchy skin. It seems to be helping with that, and, they both seem to love the flavor of the supplement. It does make their breath stink a bit more than usual, but that is to be expected. Great quality." — corndogmcp on Amazon.

"My dog is getting older (he's 8) and it's important for us to give him the best quality of life we can. He's been supplementing the fish oil for over 2 years now and hasn't showed any signs of slowing down in his joints!" — Matt Chambers on Amazon.

Dosage: Two soft chews per 20 pounds | Refrigeration required: No | Added Ingredients: Yes | How To Administer: Give as a treat

You might want to give your dog some delightful chews as an alternative to oil-based products. These chews usually have many more ingredients, and NaturVet’s offering is mainly made up of flaxseed, potato, and glycerin, with added salmon oil. 

If your dog is picky and won't eat salmon oil, these soft chews are the perfect option. Many pet owners have reported that their dogs love the taste of these chews and consider them a treat. 

Note: Since it’s not pure oil, omega-3 and 6 fatty acids concentration will be lower.

What We Like:
• Two size options (90 or 180 chews)
• Suitable for both cats and dogs
• Rich in omega-3 fatty acids
• Nor as messy as oil products
 
What We Don’t Like:
• Lower concentration of omega fatty acids means it may not be as effective as pure oils
• The potato in the treats could trigger skin allergies in some dogs
