Hi TT,
I know this isn't what your looking for (brand wise) but if you have difficulty sourcing the one you want, I can highly recommend Salmopet. It is produced near my home town in the Norwegian Fjords (and my Grandfather knows most of the people who work there,hence my happiness to recommend ;))
Ive put a link here (Ive put it on translate mode as Ive taken it from the Norwegian site)
Salmopet if it doesn't work then Im sure they have a UK site too.
You can readily buy it from most UK online pet suppliers Zooplus etc all stock it, so getting a supply is never a problem.
(I used to use Timberwolf Salmon oil)
HTH?
