Can Omega-3 fish oil help my dog's joints, skin, and overall health?

Hi, thanks for using Boop by Petco! 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/

My dog sheds a lot. Can fish oil or omega-3s help, and is it safe?

Thanks for using Boop by Petco! It is possible to cause diarrhea and gastrointestinal upset by giving too much fish oil. I really like the American journey wild Alaskan salmon oil product for this purpose. I think this product can help Buddy a lot with his hair coat. Good luck!

What fish oil is best for my dog: human grade or pet formula?

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 Boop by Petco to help you care for Chloe.

Does Petco sell Mr. Ros marine phytoplankton EPA for dogs and cats?

The experts here on the forum at Boop by Petco do not work at Petco stores and I don't think anyone would have knowledge of inventory at local stores. I cannot find this particular product on the Petco website. It's possible that it's available at your local store and you could try giving them a call. There are a number of other fatty acid supplements listed on the Petco website that may or may not be available in your local store: https://www.petco.com/shop/SearchDisplay?searchTermScope=&searchType=12&filterTerm=&maxPrice=&top_category=&showResultsPage=true&langId=-1&beginIndex=0&advancedSearch=&sType=SimpleSearch&metaData=%5BLjava.lang.String%3B%4065f965f9&pageSize=24&manufacturer=&resultCatEntryType=2&catalogId=10051&pageView=grid&searchTerm=fatty+acid&minPrice=&urlLangId=-1&categoryId=10056&storeId=10151

What's the best chewable omega-3 for my dog's skin under $30?

I like Missing Link Original. If your local Petco does not carry it you can order it online or ask you local store manager to order it for you. ( https://www.petco.com/shop/en/petcostore/brand/the-missing-link ) Hope this helps. Best wishes.
