That's the first I've heard of any problems with this oil. How about your grown dogs, did they have any trouble with it?
I fed it to my old dog for about 3 yrs and it did help her. I have a new pup and she has been getting it in her food for 2 months now and she is doing well with a shiny coat.
I had emailed the company to check to see if there was anything added to the Salmon oil and they told me, no, it is 100% Alaskan Salmon oil.

Their shipping is a standard $10 so I buy a gallon at a time.
