You are welcome, I'm glad to help you! Honestly, I'd go with the Nordic naturals simply because they are gel pills. That's because they will be easy to hide in some peanut butter or meat to give your dog. The liquid fish oil should be added to your dog's food, and if he doesn't like the taste, he won't eat the food. But if you think he will eat the food with the liquid fish oil on it, you can use the RX vitamins. I think both look good personally.

Hi, thanks for using PetCoach! I love Omega 3 fish oils is a great supplement for all dogs. It helps with the joints, skin and almost every bodily function. I prefer Nordic Naturals or VRS Omega Benefits but this product looks fine. https://www.vrshealth.com/canine-products/omegadog/

Hello. Honestly, I recommend either Nordic Naturals or Bayer Free Form Snip Tips. Both of these are highly recommended by veterinary dermatologists, too. You will need to call other veterinarians to see who carries Cytopoint. It is an excellent product & most of my clients love the convenience of only needing a simple injection once ever 6-8 weeks to control their pet's allergies.

I love Nordic Naturals and I always recommend using a veterinary product when available. They do tests to make sure you are giving the right amount for your dogs size. So while you can give fish oil from Costco I would stick to a veterinary formulation. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Chloe.

Hi, thanks for using PetCoach! I would put her on a Glucosamine AND Omega 3 fish oils. I like Dasquinn treats and for fish oils I prefer VRS Omega Benefits but it is a liquid. Otherwise try Nordic naturals. The Omega fish oils helps the joints and skin and the glucosamine is just for the joints. https://www.drsfostersmith.com/product/prod_display.cfm?pcatid=34361 https://www.drsfostersmith.com/product/prod_display.cfm?pcatid=24785 https://www.vrshealth.com/feline-products/omegacat/ I hope this helps!
