Strictly my opinion here razorseal, but this being a new pup, I would stick with a well known QUALITY formula kibble like Fromm's to promote good health. With him being so young he REALLY needs good nutrition for development.
We will be getting our new puppy in a few weeks and there is no way I would use a lesser known kibble (who knows where
they source their ingredients from) for a new little life ........
Probiotics/Prebiots in Kibble Info from Mercola Healthy Pets:
WHY PROCESSED PET FOOD CONTAINING PROBIOTICS IS A WASTE OF MONEY:
When it comes to processed pet diets, a distinction between pre- and probiotics is that prebiotics are commonly added to pet food, but probiotics can't be (or shouldn't be). If you happen to run across a pet food claiming to contain probiotics, just leave it on the shelf.
Probiotics are sensitive to moisture and heat, so if they're added to a pet food formula — especially kibble — they’ll be long dead and virtually useless by the time they make it into your dog's or cat's digestive tract. The bacteria in a probiotic must be live and able to reproduce in order for it to be beneficial.
High-quality pet probiotic supplements have some important things in common, including:
- The correct strains of bacteria beneficial for pets, not people
- Easy to give to your dog or cat
- The ability to survive the acidic environment of your pet's stomach
- Enough live organisms to colonize the intestines
- Product stability under normal storage conditions
Tests on dog foods claiming to contain probiotic microorganisms showed the manufacturing process kills too many of the live bacteria, rendering the probiotic effect useless by the time the food is packaged and shipped.
Glucosamine/Chondroitin in Kibble Info from Dogs Naturally Magazine:
All pet food labels require a guaranteed analysis on the package to advise the purchaser of the product’s nutrient content. We looked at where the glucosamine was listed and noted the following: glucosamine min. 300mg/kg.
Ok, next it was time for a little math!
Now, 300mg/kg basically means 300mg of glucosamine per kilogram of kibble. In the pet food industry, it’s generally known that, on average, four cups of kibble equals one pound. Therefore 1 kg is equal to 8.8 cups. Do you follow?
So if our average 50 pound dog needs 1000mg of glucosamine per day, we would have to feed that dog over 29 cups of big box store pet food each and every day to meet his needs!
