Glad you asked that question Miss Susanne,
Canine nutrition is how we started , oh my, almost 30 years ago? Canine fitness was a natural follow for us as nutrition reigns supreme and fitness is a very close second.
Those making treats are to be commended. However what is the base of the treat? As corn and wheat rank as the number 1 and 2 allergens in dogs I would recommend one of the numerous "ancient" grains instead.
Hailing from the B.A.R.F. camp, I would also recommend any meat given is best given raw and in its natural state. If you have a concern re. Salmonella, you can submerge meat in a lemon water bath, BUT in general this is not necessary at all. If bones are given (and I believe that they should be) they must be given raw, NOT cooked. If the meat was cooked, so is the bone. Cooked bones splinter, uncooked bones crumble.
How about vegetables as treats? Oh my, yes. However, they should be cooked as that carnivore lacks the enzyme to break down vegetable matter and must have it done for them. Whatever vegetable we were having that night, we put on extra for the dogs. Pea's especially, were pretty serious around our place. How about keeping a bowl of cooked vegetables in the fridge for the dogs? Treating with a cooked carrot was just as appreciated as other store bought treats. The bio-availability of nutrition in a cooked carrot over an uncooked carrot is very significant.
As to base kibble, I have been out of the food industry for many years now and have not kept up. However there are some basic rules for protection.
Please stop buying food from China. They have for years been showing a willingness to poison us and our pets. Yes for years. Support the American maker of the diet that chooses the best and most wholesome ingredients. Choose a naturally preserved food with NO man made preservatives. Careful about the fat and its origin. Usually the fat comes to the diet maker from a rendering plant. In the past, any preservative used by the render-er did not have to be listed by the diet maker. While tochopherols (sp?) are :"ok", it is far better to preserve with them AND Vit. C. In general, the first 4 ingeds. give you a general idea of the diets make-up. Always be aware of excess protein in a diet. Less is needed than most folk think. Unless that dog is truly working hard and for hours, choose less protein than more
Also the right sources of fat are good and necessary. Older or more sedentary dogs still need those great sources of fat, just less.
Then, don't forget the work or play which will complete the nutritional cycle. That should be the most fun part of feeding or building your own diet.
