Does dog food's fish oil oxidize and lose omega-3s if open a month?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! If the bag containing the food was air tight and non-pourous it is likely fine. Even if it wasn’t stored with essential oils, 3 months is a long time to store dog food. We worry about mold formation and these foods usually have an expiration date. I’d remove the food from the closet with the essential oils. If it smells like the oils when you open the bag, discard the food. Have a good day

One fish oil capsule a day is fine. There is a risk of giving your dog too much fish oil, and there are serious side effects from that including a tendency to bleed more when injured due to the fish oil interfering with platelet function, interfering in wound healing, and an interference in the inflammatory response of the immune system. I would not add any fish based kibble due to these risks.

The dog food may be "fresh" and palatable, but it will have lost some aroma and definitely a lot of the vitamins. Usually Vitamins stay actively working for about 6 months, so if you have a bag that has been opened for longer than 6 months the quality of the food is less than when it was originally opened. You can feed the food, but realize, that its nutritional value may be lower than when the bag was opened. If the manufacturer tells you that after 18 months the food was as good as when it originally was opened, you want to see the respective research proving that. In my professional opinion: the faster you use up the food after opening, the better.

The recommendation of how long a food lasts is usually arbitrary and often not based on any studies, so it's difficult to say how accurate this information is. Of course, storing food for a long time can lead to infestations and growth of harmful microorganisms, but this depends on how the food is stored and the climate you live in.

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/

Not sure but I think I did!! Fish oil is not needed as long as her food is of good quality. That ratio seems balanced and ok. Please do not hesitate to contact us again on the forum or by requesting a consultation (where you can post pictures ) if you have any more questions or to discuss it any further.

Hello. Dog kibble has organic compounds like fats, just like any other perishable food might have. Generally, if a kibble is not used within a month , it is a good idea to put the remainder in the fridge or freezer to prevent the breakdown & loss of essential vitamins & nutrients & rancidity of the fatty acids. As long as the original package seal is not broken, a food might remain relatively fresh for months, but once opened, it is good to try & use the entire contents within 4-6 weeks.
