Fish-Free Omega-3 for Senior Dogs

Two different omega-3 supplements causing vomiting is a real red flag — and it usually means it's the fish oil itself, not just a dodgy batch. Before I suggest anything, can you tell me a bit more about your Bichon? How old is she, and is the vomiting happening shortly after the dose or a few hours later?

That consistency across two different products really does point to fish oil being the issue rather than a filler or preservative. Same reaction with both liquid and capsule form is pretty conclusive. Is the omega-3 mainly for her joints, her coat, or both? And has she had any other digestive sensitivities — like being fussy with certain proteins in her food?

That's really helpful. For a 13-year-old Bichon with a sensitive stomach who needs joint support without fish oil, I'd point you to YuMOVE Advance 360 for Dogs. It contains green-lipped mussel as its primary omega-3 source rather than fish oil — green-lipped mussel is a shellfish, so it's entirely fish-free, and it's significantly less likely to cause nausea. It also includes glucosamine and hyaluronic acid which directly support joint cushioning, which is exactly what you need for a dog her age who's starting to slow down. The tablets are small enough that most small breeds take them without fuss, crushed into food if needed.

It's genuinely well-supported. Green-lipped mussel has a stronger evidence base for joint inflammation than standard fish oil does, actually — it contains a broader range of omega fatty acids including some unique ones not found in fish oil. It's been used in veterinary joint supplements for over two decades and there's good clinical data behind it. The fact that it comes from shellfish rather than fish also explains why dogs who react to fish oil usually tolerate it well. I'd give it four to six weeks to see meaningful joint improvement — it's not an overnight fix, but at 13 it's absolutely worth doing.

I'd start at half the recommended dose for the first week, just to let her system adjust — not because green-lipped mussel commonly causes issues, but because her stomach history warrants a bit of caution. Give it with food rather than on an empty stomach. If she tolerates it well after seven days, move to the full dose. Given her age and size, the standard senior dosing on the pack should be right for her, but your vet can confirm if you want a second opinion on the amount.
