Hi, the supplement which is a blend of fish and seed oil, keeps her coat healthy and joints supple. There are loads of brands on the online pet shops in Oz that do the plant type Omega oils but you still need the addition of fish oil for the missing Omega number - I can't remember which. If you have a dog, try it, you will notice a huge difference in a couple of weeks. Also and sorry to be gross, but their motion improves tool.
