Hi DieselJunki –
Nature’s Logic is a great product and I have a lot of trust in the company. My cats eat Nature’s Logic kibble and when my oldest dog used to eat kibble I used the Nature’s Logic canned food as a topper quite frequently. I’m also a big fan of their whole food supplement and occasionally use it in my rotation (although I’ve mostly gone to formulating my own supplements lately..).
Unfortunately, all of the Nature’s Logic foods are MUCH too high in calcium for a large breed puppy (I’d wait until your pup is at least 6 months old and through his rapid growth phase before trying this food). Generally, in order to get the actual calcium level you have to call or email the company because most companies only list the minimum calcium percentage on their packaging and website and often the actual calcium percentage is much higher than the stated minimum. Nature’s Logic, however, is one of the few companies that discloses actual nutrient levels on their website – the reason I know they’re actual is because at the top of the analysis for each food it say “Actual Analysis Units Dry Matter Basis” and there’s no “min” before the calcium percentage. All of their dry foods are 2.123% calcium and well over 5.5 g. ca. per 1,000 kcal.
When I compiled my calcium list I called or emailed every company with a grain-free food rated 4 or 5 stars on DFA. Some companies never responded to my emails, didn’t pick up the phone or wouldn’t disclose the actual calcium level so it’s possible that some 4 or 5 star grain-free foods are appropriate and not on the list, however I think I’ve covered the majority. If you do call a company to get the calcium levels be sure to ask for the actual level and make it clear this is what you’re looking for (otherwise they may give you the minimum). If they don’t have an actual level from a lab analysis ask for the maximum and calculate values based off this.
