Is Ketona a "Ketogenic" Food?

That depends what you mean by "ketogenic."

We can't guarantee anything specific about your dog's ketone levels (because the extent to which a dog's body produces ketones is influenced by a number of factors other than whether the dog eats Ketona), but it's likely that dramatically reducing your dog's carbohydrate intake will increase her production of ketone bodies to at least some degree.

As you can see from this study, dogs tend to produce some amount of ketone bodies even when fed a high-carbohydrate diet. So, in a literal sense, just about any canine diet is probably ketogenic, at least to some degree. But dietary interventions such as carbohydrate restriction, overall caloric restriction, and supplementation with MCT oils tend to ramp-up the process even further.

It's unlikely that simply feeding Ketona will cause your dog to enter a deep, therapeutically ketotic state. So if your aim is to maximize the amount of ketones in your dog's blood for one reason or another, you'll probably need to do more than just switch to Ketona. 

But, all else being equal,  switching from a garden variety kibble to Ketona is likely to increase your dog's production of ketone bodies.
