I’ve been making these for a long time now. My dog, Lola, knows by the smell when I’m baking for her and is in the kitchen the whole time! To make it easier, I use a pizza cutter and make 1x3” long strips instead of the bone shape. It is much faster with less rolling and these strips fit very nicely into Lola’s Kong. I use all natural peanut butter, and if I remember, get it freshly ground at the grocery store. I also buy the real Ceylon cinnamon to avoid any coumarin overdose if I give her too many treats.
The root to such mistakes is usually in the fact that owners assume dogs can eat almost everything we can, and it may be healthy for them. And while it’s true that dogs are omnivores, have stronger stomachs than us (in some ways) and some human foods are extremely good for them, there's a number of food items you should be careful about when preparing your dog’s next dinner.
All of the above dog food recipes will be deficient in many essential nutrients. There is no significant source of calcium or adequate sources of micronutrients such as B vitamins, vitamin D, etc. In addition to lacking calcium, the calcium:phosphorus ratio is an important consideration. Please consult your veterinarian before feeding any home diet. These are not adequate!!
