Some grain free kibbles I have used that are very small and what I feel are quality fish based products are as follows:
Nature’s Logic Sardine (protein 40.2%);
Canine Caviar Wild Ocean (protein 31%);
Pulsar Fish (protein 28%) is small, but not super tiny;
and EVO Herring & Salmon (protein 42.98%).
OK, the EVO I mention is one to use with caution. Yes, EVO did just have a recall (their first in 21 years I understand, but not surprisingly already their first since their acquisition by P&G in 2010) and I don’t know about ingredient sourcing, but I’m using it right now (for my grain and white potato free dog) and we’re having very good luck with it. A shame though, EVO was once a fantastic product with a reputation to match.
I’ve also used Horizon Legacy Adult with amazing success and love it, but I haven’t used their Fish formula (although I’m eager to try it). The Adult kibble isn’t small, but isn’t huge either, and I have no idea what the size of the fish kibble would be.
Orijen Six Fish is great, but probably one of the biggest kibbles.
I don’t know about the size of Earthborn’s Coastal Catch, but they’re a company I trust also.
