I am going to try and make this as short as possible cause Lord knows I tend to ramble all the time

To cut to the chase, I have taken both of my kiddos off NV Raw and put them on Natural Balance Potato & Duck (they are both doing EXTREMELY well on it and Tatum is itching SOOOO much less!!!

YAHOOO!!!)
However, now that they are eating the dry kibble, neither one of them like the Salmon Oil squirted on top of their food. They were totally fine with it when I put it on their Raw in the morning, but they DO NOT want to eat their dry food when the Salmon Oil is on there.
So, my question is this. Is there anything else I can give them that will provide the same benefits that the Salmon Oil does?? Maybe possibly in a DRY/SPRINKLE formula??

Or even a liquid that they might like the taste of better? I don't want to totally stop the supplements, but I can't force them to eat it if they don't like the taste of it
P.S. - Tatum has really bad allergies, so I need something that isn't going to interfere with that.
Thanks in advance!!
