    Purpose: Multifunctional
    Lifestage: Adult to senior

    Zesty Paws is a well-known brand for making a wide variety of high-quality supplements for cats and dogs. Out of all its products, one of the best overall supplements for dogs is the Zesty Paws 11-in-1 Multifunctional Bites. These chews are loaded with all kinds of good things for your pup.

    These 11-in-one chews are the upgraded version of its past eight-in-one easy-to-feed chews. They have been packed with even more goodness for your dog. They are meant to support your pup’s broader functioning in life. The chews do this by supporting your dog’s immune and digestive systems, the health of their skin and coat, and their heart and organ health.

    The chews contain vitamins and nutrients necessary for a dog’s continued health, like vitamins A, E, B, and C. They have chondroitin and glucosamine and OptiMSM to help encourage the mobility and continued comfort of the hips and other joints. In addition, folic acid and CoQ10 are included to support the heart. What’s more, since these chews are soft and chicken-flavored, your dog will be begging for more instead of spitting it on the floor.

    • Full of essential vitamins and nutrients
    • Upgrade of the eight-in-one vitamins
    • Chicken-flavored and soft texture beloved by dogs

    2. Nutramax Cosequin Maximum Strength with MSM — Best Value

    Purpose: Small dog joint supplements
    Lifestage: Adult

    Nutramax Maximum Strength with MSM Soft Chews are excellent for those pet owners who want to encourage health in their small and toy breed dogs. They are easy for small dog breeds to eat because they are made small for their mouths.

    They are also moist and tasty, acting as treats for your dogs instead of nasty vitamin pills. Most dogs like them, although there is evidence that if your pup has had a health condition that affects their appetite, they might not be as interested in them.

    These chews are not as focused on overall health, as they support joint health for your little pup. In addition, they have a unique formula that contains glucosamine and chondroitin. These two nutrients encourage continued mobility in your pup’s joints and cartilage health.

    These soft chews also contain omega-3s that support your dog’s healthy skin and coat. Currently, they are on lists as the number-one veterinarian-recommended brand for joint support for small dogs. What’s more, these are the best supplements for dogs for the money.

    Purpose: Joint health
    Lifestage: Adult

    Often, when you discuss supplement options with your vet, you will look at the viability of both Cosequin and Dasuquin for your pups. These are easy-to-feed soft chews that you can give to breeds ranging from small to medium dogs or those dogs that are under 60 pounds in weight.

    Nutramax has developed these Dasuquin with MSM Soft Chews after 10 years of clinical use and research. It has used its research from its version of a Cosequin joint health supplement to develop the Dasuquin formulation for dogs. Although this is a cost-effective formula, when comparing other Dasuquin products, you are praying a premium price for highly effective joint support.

    Dasuquin works by combining NMX1000 ASU and a decaffeinated tea made up of glucosamine hydrochloride and low molecular weight chondroitin sulfate. It’s meant to stimulate cartilage matrix production to continue the health of joints and interior cartilage.

    • Wide range of ages and breeds
    • Made of a dual synergistic formula

    A team of nutritionists, veterinarians and researchers helped identify the perfect amounts of nutrients to balance live microorganisms. The supplement is in the form of a powder.

    These chews work by stimulating a typical histamine response instead of allowing allergies to wreak havoc on their system.

    Pros
    • Probiotics and turmeric help encourage digestive health

    Buyer’s Guide

    Finding the right supplements for your dog depends primarily on what breed they are, their age, and their overall health. Pay attention to what your pup needs and how their health might suffer. For example, certain breeds will have a more significant propensity for joint issues and cartilage issues. Other dogs that suffer from allergies will need help controlling their symptoms.

    Essential Vitamins for Dogs

    Dogs need specific vitamins to stay healthy, such as glucosamine and chondroitin. If your dog doesn’t get enough nutrients in their typical meals or has a vitamin deficiency, you might need to supplement their diet with vitamins and nutrients in a supplement.

    Ongoing Health and Considerations

    You might need to talk to your vet about your dog’s dietary needs and if they need anything else to cover their total dietary needs. However, as long as your dog is eating a balanced diet, they are probably fine. If you feed them a raw diet, you might need to use multifunctional supplements that help round out their diet.

    Age Range and Weight

    You should consider your dog’s age and weight bracket — i.e., whether they are a small, medium, or large breed — before choosing your supplement. Some are only geared toward specific age groups or weight brackets. If your dog doesn’t fall into these or if you give them the wrong dose, it can cause diarrhea and other unhappy digestive issues.
