Cat doesn't take it down

I think the product is excellent, but unfortunately I can't speak to its effectiveness because my cat doesn't take it in. She turns her nose away and walks away from it.

Lemon Flavor Was A Bust

As a dog mom, I wanted to love this product. My dog absolutely did NOT love the lemon flavor/scent. No matter what I tried... Herculean efforts and fantastic disguises would not make this product even tempting to my dog to consume. It was a bust. We've gone with a different brand that smells like fish, and she loves it. It's too bad. I'm sure it's a great product and we love our other supplements from Nusentia. Just not this one.


I’m a returning customer. I think this is the best fish oil for my dogs. I tried a couple different ones, but won’t try any other anymore. This is it!

Best fish oil

This stuff is amazing. I have tried other fish oils but always end up coming back to this one. It makes their fur so soft and shiny. I use this with the probiotic and enzymes.

Not for my dog

I am afraid my Dog didn't like it, would not go near his food. Tried feeding him without it and he ate it all. Disappointed, sounded very healthy. Didn't want to use syringe and force him if he didn't like it.😟 but it was shipped securely and arrived quickly.
