K9 Complete 8-in-1

32 oz.
Most pet’s commercial diets are woefully deficient.  Attempts to make up for these nutrient deficiencies by adding cheap, “feed grade”, non-bioavailable vitamins and minerals to dog foods or feed supplements don’t come close to filling in the gaps of what modern science has shown is ideal for your pet’s health and well-being.  This is where K9 Complete, a multivitamin for dogs comes in.

    Good health prevents vet visits

    I love this product and my chiweenie does too! I prepare all his food at home and with the addition of K9 Complete I feel he receives all the necessary vitamins.

    nice mix

    I showed this mixture to our vet and he said it was a good mix. His only concern was the lack of directions on how to administer it. Dosage directions were given, but how do you give it? He said NOT to put it in water as it would quickly turned the water into a less than desirable bacterial soup. He said leveling it on the food (our dog free feeds) was also problematic. We ended up using it as a liquid treat and letting him lick it off a spoon. He likes the flavor and we have not had any intestinal issues so far. He is shedding right now so difficult to judge how it will affect his coat. So far we are pleased with how this works.

    He Likes the Flavor

    I like to believe that I feed my dog a healthy and well balanced diet but it is nice to have have a backup plan as a form of insurance just in case he is lacking is certain unseen nutritional areas. This just gives me a little more peace of mind that I am doing the best I can to provide for him. He is like a child to me and I want the best, health wise, for him.

    This seems to cover all the bases as far as the nutritional needs of a dog are concerned, although I am no vet. The ingredients seem to be of good quality and and he certainly likes the taste of it. I like to add this to his dry and wet food.

    My dog falls into the 51-70 pound category so I give him the recommended dosage of 1 1/2 TBSP. Specific dosage sizes are on the back of the bottle and I have also included a picture for your convenience.

    Hope this helps!

    Dog Readily Eats This Bacon Flavored Supplement

    I prefer liquid supplements over pill-form any day; our dog seems to have the same preferences. He spits out his allergy medication, so it gets hidden in his dog food. Since he’s an old-timer, I wanted to incorporate a multivitamin into his diet as well, but knew one more pill would be tricky. K9 Complete has been the perfect liquid solution, and this formula not only contains vitamins and minerals, but other important nutrients. Jack eats his food with gusto—he must really like the bacon flavor in this. When the bottle first arrived, I tasted some on my finger. It really is very palatable, and I think he likes the added moisture to his meal as well as the flavor. Feeding is based on weight–look at one of the Amazon product photos for complete directions. This is convenient as well as economical (big 38 oz size).
