We took Willow to the vet today to see what was up with the dandruff. It was diagnosed as severe dandruff and the vet gave us a free form liquid, "a free form fatty acid offering maximum potency of EPA and DHA [Omega-3's for Dogs and Cats]." We came home from the vet, gave her her prescribed dosage and went about our day. Well, about three hours after it was fed, she puked up her entire lunch. Bane had gotten into her food and MAYBE had a bite of her food; he too puked about 30 minutes after she did. Has anyone else had any issues with Omega-3's doing this? We're afraid to give it to her tomorrow with her lunch in case the same thing happens. I figured, I could call our vet on Monday since they are closed on Sunday's. Thoughts or ideas would be appreciated!

Nope, but I use capsules not oils. Have you tried capsules instead?

I use salmon oil, and have never had a problem, but I've never tried capsules.. It just seems strange that both would have this reaction. Could it be that it's rancid? I know you got it from your vet, and the hope would be that it's not, but you never know. I would try either capsules like Megan said, or go buy a human grade fish oil.

I use NOW brands salmon oil and have never had an issue

My lab has dandruff and since she was little I add Wellactin (liquid fish oils) to her am meal. She has never had a problem with it. It has helped her dandruff a lot!
