Dibo Salmon Oil - dog supplements

It smells like hot-smoked salmon and doesn’t do any good, but apparently it tastes nice.

I’ve used this for a while and haven’t noticed any difference in my dog’s coat. I decided to look it up and it turns out there’s absolutely no transparency about the ingredients. It only says 100% salmon oil, but the omega 3 values, and especially the DHA content, aren’t mentioned… I like to know exactly what my dog is getting.
