Vertex High-Performance Dog Supplement – Predigested Liver, Whey & Egg Protein – Supports Muscle, Recovery, Fertility, Digestion & Milk Production – Ideal for Working, Breeding & Active Dogs - 10LBS

I've been raising & showing American Pit Bull Terriers for the last 25+years. These days at the ADBSI Sanctioned shows, you have to bring your dogs in tip, top notch condition if you plan on bringing home any 1st, 2nd, 3rd place ribbons, or any hardware (trophies or CH Cups) for that matter. I started using CPN's Vertex and CPN's Structure for the younger pups (under a year old) about 6 months ago, or so, and I must say that I am extremely impressed with these products! After doing lots of research on CPN'S products, and their competitors products (K9 Superfuel, NuGold, etc...) I found that CPN put in more more R&D into their products, and offer a far superior K9 supplement than their competitors. VERTEX has the perfect balance of protein, crude essential fats, carbs, amino acids, electrolytes, fiber, essential vitamins & trace mineral s, etc... it's truly is the complete package of canine supplements, and definitely shows in the conformation ring, top dog athletic event, weight pull competitions, workout regimens, etc... I noticed a huge difference in about 2 weeks of steadily using Vertex. I will continue to use these products for a very long time, and definitely will recommend these product's to anyone looking to make that difference, a cut ahead of the competition! I now use CPN'S STRUCTURE for all of my pup's under a year old, and really think it's showing a better more healthy pup with a shiny coat, lots of energy, and cut, even though we do not work the puppies very hard.

Been using this product for years and haven't had any issues with any of my dogs... This supplement has so many benefits that you wouldn't believe..

We put our senior dog on this and she acts like a puppy! Great product.

This stuff is amazing. Got my older GSD when she was almost 6. She was the loudest walker I have ever heard. This was because she dragged her feet. Thought that was normal, I never had a GSD, later found out it is not. The owner took good care of her. I got a GSD puppy and found a dog trainer, Deschutes K9, she recommended this. The older dog, Maci no longer drags her feet and she is almost 9!! Had her senior vet check and they did heat signature tests on her and she only had slight signs on knees, elbows and her back above her hips. The vet was so impressed. I have my 6 month old on this and Structure, made by the same people just for puppies. The puppy is the black one in the picture. This is after hiking up a mountain on rugged terrain. Highly recommend!!

So I read the reviews before I purchased this product to see what everyone's opinion was and this here is my own experience..... The new plastic bag that it comes in is really not use full. On their own website it shows it in a new plastic bag. Amazon still has an old photo of the jug. An because with the settlement of the power through shipping you have to fish around inside of the bag to find the tiny scoop. Then it would not seal up properly cause of the grains of product in the zipper. So I kept the 4lb plastic jug from the last product I had ( in which I'll never use again) And poured Vertex into it. Now iam happy 😊 But the biggest and main thing is my dog loves this stuff ! When I mixed this up with his water, he didn't hesitate to drink it

I was having trouble putting weight on my 9 year old Doberman even though she eats well. She’d get loose stools if I upped the food amount. A friend shared this product with me and she likes the taste of it added to her food. Now she’s back up to a good weight AND she’s more active. I didn’t think she was having joint pain but she had become less playful. I blamed it on her age but now that we’re on our 2nd bag of this product she’s a lot more playful and is obviously enjoying running around and even initiating play with my 2 year old Doberman. I recommend starting out slow and upping the amount gradually until you know your dog will tolerated it well. I know I’ll be buying more!

This is the second time this has happened to me ordering off Amazon. Unsealed bag is sent! Vertex the supplement itself is an AMAZING product! I’ve used it for years & years and it is hands down one of the best, if not the best, working dog supplements on the market. HOWEVER this seller is horrible! They don’t allow refunds, returns, or exchanges and sent me a defective bag that was unsealed! It was opened from a manufacturer sealing error. Supplement spilled during shipping. No idea how long it’s been sitting open in the warehouse. Why send a defective product! This has happened to me twice now ordering this supplement off Amazon. I reached out to CPN to let them know this is happening with their products on Amazon. If it happened to me at random twice back to back how often is this happening to others?? I understand mistakes happen but not allowing returns or exchanges for a clearly defective product is not okay.

Good supplement for working dog maintenance. My dog loves this in his meals or mixed in water.
