Maximize Your Dog's Nutrient Absorption and Support Healthy Digestion
VetSmart Formulas probiotic provides all the benefits of a high-quality veterinarian prescribed probiotic, and is also designed to enhance the absorption of nutrients, specifically the nutrients found in the VetSmart Hip + Joint Complex.
How? The heart of nutrient absorption lies within your dog’s gastrointestinal system and proper digestion.
If you optimize digestion and remove the things that may be inhibiting absorption within the gastrointestinal system, your dog will reap more of the benefits from the supplements and nutrients they consume.
Order NowWhy is the VetSmart Product Better?
VetSmart's Probiotic Nutrient Enhancer is specifically designed by veterinarians to deliver maximum potency and maximum benefits to your dog! Here are several reasons why:

The VetSmart Nutrient Enhancer contains more than 15 billion active cultures, as compared to most probiotics that contain 1 to 5 million. This ensures your dog will gain all the benefits necessary from the VetSmart System.
VetSmart's formulation experts selected the best strains of active bacteria cultures for your dog, taking into account canine body chemistry. The result is a proprietary blend of active bacteria strains sold exclusively by VetSmart Formulas.
The cultures within Probiotic Nutrient Enhancer are microencapsulated to ensure that the beneficial active cultures are alive when your dog consumes them, and are designed to survive the journey through your dog’s stomach to its intestines.
Probiotic Nutrient Enhancer is shelf-stable and does not require refrigeration. It’s mildly flavored with natural beef liver, and easily added to your pet’s diet. Simply open the capsule and sprinkle the probiotic on your dog’s food.
No More Diarrhea or Upset Stomachs!
All dogs can benefit from probiotics! A good probiotic will:
- Treat diarrhea and irritable bowels;
- Reduce intestinal inflammation;
- Help aid the digestion of food and absorb nutrients;
- Reduce allergic reactions such as constant licking and scratching;
- Inhibit the growth and activity of harmful bacteria;
- Prevent urinary tract infections;
- Modulate the immune system and more.
Dogs are just like people, and stress can upset their stomachs. So when your dog is stressed from being sick, traveling, staying at a kennel, or other life interruptions, its digestive system can become irritated, causing cramping, gas, diarrhea, and vomiting. Probiotics stabilize the gut and quickly get your dog back on track!
Also, for dogs taking antibiotics, probiotics will reduce unpleasant side effects of the antibiotics, such as bloating, diarrhea, and gas. These side effects can lead to lethargy, loss of appetite, and having your dog feeling depressed and miserable.
What Are Probiotics?
Probiotics are beneficial bacteria that live in the digestive tract and have been used for centuries to maintain a healthy intestinal tract.
The term probiotics originates from the Greek word that means “for life.” When ingested, these living microorganisms replenish the microflora in your pet’s intestinal tract. This results in the promotion of a number of health-enhancing functions, including enhanced digestive function.
There are plenty of foods that contain natural probiotics. Foods such as yogurt, leeks, onions, bananas, sauerkraut, honey, and garlic all contain certain amounts of probiotics. However, most of these foods are not ideal for dogs.

Frequently Asked Questions
Call your vet immediately and explain the situation. If your vet is not available, contact the ASPCA Animal Poison Control Center at 888-426-4435.
Your dog’s stomach acid and bile are very strong and kill some of the active cultures that your dog needs. We formulated our product with 15 billion active cultures to ensure that enough of the active cultures survive the journey to the intestines where they are absorbed into your dog’s system.
Probiotics are a population of good bacteria that belong in your pet's gut, working together with the cells of your pet's gut in order to keep those cells happy and healthy. When there's a deficiency or an imbalance, the gut becomes permeable (holes form in it), and/or it becomes inflamed and allows abnormal proteins to get through to the blood stream. This may cause your dog to develop allergies to foods and sensitivities to environmental substances. That is why probiotics are so important. They balance the natural chemistry in your dog’s gut and digestive system.
Probiotics are also anti-inflammatory. They prevent inflammatory bowel disease and make sure that other types of bacteria don’t create problems like overgrowths of salmonella or yeast organisms.
YES!! In addition to all the great benefits of probiotics, another advantage to our Probiotic Nutrient Enhancer is that it's designed to work within the cell structure to help open the cell walls and assist your dog in absorbing the nutrients in our VetSmart Formulas Advanced Hip + Joint Complex. This delivers more effective and powerful benefits and results. We call this the "Power of Two"!
All our products are proudly made in the USA. We use all-natural ingredients that have been well-researched. We also follow AAFCO (Association of American Feed Control Officials) and FDA-CVM (Federal Drug Administration – Center for Veterinary Medicine) guidelines. Our manufacturing is in FDA registered and audited facilities, they are audited by Underwriters Laboratories (UL) and are fully compliant with cGMP standards. This ensures that we control the ingredient and manufacturing practices to deliver consistently safe and effective products to our customers.
Veterinarians typically sell products that are stronger and more effective than what you might find in a retail pet store. The products are better formulated, and they contain more of the powerful “active ingredients” that are so helpful in delivering the benefits to your pets. Vetsmart Formulas products are specifically developed for Veterinarians and we are proud to call them “Veterinary Strength.” Our products meet the most demanding standards required by veterinarians and we conveniently deliver these products directly to you. Our products are not available in retail stores. They are made in the U.S.A., they contain no artificial colors or fillers, and are wheat and gluten-free.
For dogs taking the once-daily dose, one bottle will last 30 days. However, the dosage is different depending on your dog's weight. Please review the label above and determine the correct dose for your dog.
If, at any time, you're not completely satisfied with our products, return the unused portion for a complete refund.
No need for a reminder. We’ll make sure your pet has a consistent and fresh supply of supplements to keep them healthy! Sign up for our convenient Auto-Ship program and we'll automatically ship you a new supply each month — with no shipping charges.

LOVE these Probiotics!!!!!
I researched practically every option on the market and found these probiotics to be the best of quality compared to all the rest for my young Saint Bernard. Most especially considering, the ingredients are f top quality and love the fat that they do not have any chicken or other allergy triggers in them so giving my dog a pure probiotic to boost his overall wellness gives me peace of mind. True test: My dog has been taking them for several months now and because he is also on an excellent diet, the probiotics have been an amazing supplement as they have truly helped resolve his underlying skin issues, while also helping boost his immunity & digestive system, which is a huge bonus for us!!! Excellent product and a must have for us everyday!!! Happy boy & happy me!!!
