My main reason for asking is because I recently picked up a sample of Fromm's Surf and turf which is a grain free kibble and the kibbles are little in size like the Solid Gold Wee bits he was on. I have switched him over in the past two weeks or so because he just seems to love the new kibble but I want to make sure its okay.
He actually seems less constipated like his "poops" are slightly softer and just a tad larger since switching...??

The ingredients look great:
Fromm Family Foods - Four-Star Grain-Free Surf & Turf for dogs
It looks like the protien content is about 30% is that too high??
