Zamboni, my beagle/spaniel, will be 15 in May.
I've been feeding her 1/2 home cooked and 1/2 kibble. Both grain free. But her stools are getting soft on that combination. I think she's just getting a little too old for this rich of a diet. I've tried both the high protein/fat combination of Instinct, and the high carb/low protein/low fat combination of Natural Balance Fish/Sweet Potato. I've also tried mixing these for a balance. Nope.
When I drop the home cooked to about 1 Tblsp (which doesn't add much besides flavor), her stools firm up. But then she's just basically eating kibble, and loses the nutritional benefits of the organic home-cooked diet, which is mostly turkey, chicken, or buffalo (she can't tolerate beef , pork, or elk well anymore), plus a wide assortment veggies.
I'm nearly positive that if I switch her to a kibble that has grains (which would add bulk), I could continue to add the home-cooked and resolve the problem.
Boni has to watch her weight carefully, which is part of the reason I switched her off grains. (Also, my GSD is highly allergic to all grains, so I wanted to ensure that he didn't find a runaway piece of kibble that would be "toxic" to him.) She can't tolerate anything raw, not even raw eggs.
So, what do you recommend? Stick with grain free kibble and minimize the home cooked? Or move to a kibble with grains and continue with cooked diet? Or, none of the above and other suggestions?
