fishy smell

Sad to say my horse won't touch this stuff- it does have an initial smell of mint, but then there is a strong (and long-lasting) fishy smell. I got some on my coat

Sad to say my horse won't touch this stuff- it does have an initial smell of mint, but then there is a strong (and long-lasting) fishy smell. I got some on my coat and it persisted for days. I really hope my dog will eat it, since I hate to waste it!

I’m an equine scientist and nutritionist, and I appreciate this formula of digestible fish oil. It has a great Omega 3:6 ratio and is a source of healthy fat. It’s peppermint flavored so the horses eat it when I pour it on their beet pulp and other supplements.

I’ve been playing around with supplements for my OTTB and this absolutely transformed his coat. My horse is also low in his field hierarchy and often gets minor cuts and scratches when he’s pushed around by the horses and this oil not only transformed the lustre and texture of his coat but also improved the healing of these scrapes. The shine speaks for itself, this is now a permanent fixture in his diet. It took at least a month of daily supplementing until I noticed a difference so if you’re considering this supplement, give it time to work

Palatable and great source of Omega 3

Even my picky horse will eat this oil. Coats are shinier and my horse with allergies has seen an improvement in her inflammation.

My equine nutritionist recommended KER EO3 oil to help with inflammation and glucose tolerance for my two horses. I was doubtful they'd eat this fish oil product, but slowly introduced it over 3 weeks. I started with a 5 cc syringe mixed into their alfalfa pellets, working up to the full ounce. They love it, even licking their grain bowls clean. They've been on it for about 2 months and I'm already seeing shiny coats. I found chewy to have the best price for this 32 oz bottle, and by far the fastest delivery of any of the equine suppliers. Big yes! from me and my horses!

The EO-3 has the DHA and EPA I was looking for to help my horse with her coughing. However... she will not eat it in her food. I stopped putting in her food, but now she is reluctant to eat. I then started drawing up 15 ml and giving it by mouth. I guess it affected the taste of her feed and hay. She wouldn't eat for about 30 minutes. After the third day, she refused to take any more of it. So disappointed. Maybe there is a better way to get her to take this and it not be a bad experience. Right now I've got to work on regaining her trust.

My horse has a history of repeated eye ulcers. Since using this, i have seen a marked decrease in the number of painful ulcers in his eyes! When they have flaired, I have been able to manage them with the medication protocol the vet gave me, and have not had the vet out to look at his eyes in months!

My TB’s coat is shiny and I think it helped his weight as he is a hard keeper.
