    Fresh-K9 Max Strength is a 100% natural electrolyte supplement for dogs, supporting hydration and recovery for pets and sports dogs that need a boost! Created by vets and trainers, our tasty chicken flavoured drink is energy rich and electrolyte filled, helping to replenish fluids and minerals. The all-natural ingredients in our electrolyte powder for dogs have been formulated for maximum absorption and a quick source of energy, in a powder format to ensure they remain refreshed, replenished, and ready for action. Ideal for active dogs, and keeping dogs energised in hot weather, the electrolyte rich Sodium, hydrating Potassium and energising Dextrose combine to regulate your dog's fluid balance, support muscle function and cardiovascular health. Where there is no need for extra energy, you can also mix a smaller amount of powder into water “to taste” and help make water more appealing on hot days – even for the fussiest of dogs who turn down plain water.

    How will a rehydration supplement like Fresh-K9 Max Strength help my dog?

    +

    Just like humans, dogs need to stay hydrated to perform their best. When dogs exercise or are exposed to warm weather and hot temperatures, they lose essential fluids, leading to dehydration. This can result in fatigue, overheating, and longer recovery times.

    By replenishing lost fluids and electrolytes, we can help support our dogs and ensure our trusted companions stay fully hydrated, active, and healthy, whether they’re competing at dog sports, running in the park, or cooling down after training on a warm day.

    Fresh-K9 Max Strength is packed with natural ingredients perfectly aligned to the daily electrolyte requirements of a dog and is formulated to help rehydrate your dog quickly and effectively.

    Using Fresh-K9 ensures your dog stays hydrated and active, while also supporting faster recovery, so they can keep enjoying their favourite activities without missing a beat!

    Is this dog supplement suitable for all breeds, ages and sizes of dog?

    +

    Yes! During the period of exercise, Fresh-K9 can be given several times a day in small amounts to sustain the energy level of your dog.

    Where there is no need for extra energy, you can mix a smaller amount of powder into water (to ‘taste’!) to make the water more appealing.

    Fresh-K9 pairs really well with Brothy-K9, Shroom-K9 and Probio-K9, specifically where hydration and gut-health is a focus.

    What is in Fresh-K9 Max Strength?

    +

    Fresh-K9 Max Strength is a hydration and energy support formula for dogs that’s packed with essential electrolytes, functional superfoods, and amino acids to fuel your dog before, during, and after activity.

    Here’s what’s inside each scoop:

    Electrolytes like Potassium, Calcium, Sodium & Magnesium – to replace what’s lost through panting and movement

    Brewers Yeast – packed with B vitamins to support energy and metabolism

    Soy Protein & Glycerol – for muscle support and hydration retention

    Spirulina & Ginseng – known for their antioxidant and endurance-boosting properties

    Lion's Mane Mushroom – supports focus, clarity, and brain function

    L-Arginine – an amino acid that supports blood flow and stamina

    Chicken flavour – because dogs deserve tasty hydration too

    Each serving helps support hydration, stamina, and post-exercise recovery, so your dog can perform, recover, and feel their best.

    Supplement Composition per 1g
    Fat 28g
    Carbohydrate 23g
    Protein 18g
    Dextrose 25g
    Glycerol 8g
    Citric Acid 1.5g
    Potassium Chloride 500mg
    Calcium 500mg
    Sodium Chloride 100mg
    Magnesium 75mg

    My dog is on a special diet. Can they still have this?

    +

    Yes! This works with any diet. The formula is designed to assist your dog’s gut, not upset it!

    How do I give this supplement to my dog?

    +

    We’ve produced Fresh-K9 as a powder supplement so you can easily transport it dry and mix with water wherever you go, or mix it in advance. It can even be frozen for a cooling and hydrating treat.

    It is recommended to start Fresh-K9 1-2 days before intense exercise or competition – or when needed for extra hydration.

    Fresh-K9 can be given several times in small amounts to sustain the energy levels of your dog. Where there is no need for extra energy and you are simply supporting your dog’s hydration, you can mix a smaller amount of powder in water “to taste” and watch your dog actively choose to stay hydrated!

    Electrolyte Loss in Dogs

    Yes, when dogs become dehydrated, they lose electrolytes such as sodium, chloride, and potassium. These electrolytes are critical for several physiological functions, including:

    • Muscle action
    • Nerve function

    Key Findings:

    Studies show that electrolytes are primarily lost in saliva during exercise. The duration and intensity of aerobic exercise may influence changes in salivary electrolyte concentration. This suggests that replenishing electrolytes can help prevent dogs from experiencing electrolyte imbalances, particularly in cases of extended or repetitive aerobic exercise [1].

    Heat tolerance in dogs is influenced by their hydration state. Under controlled activity in moderate heat and humidity, dogs accustomed to work and the environment were more likely to increase fluid consumption when offered a flavored oral electrolyte supplement [2,3].

    Can I feed Fresh-K9 Max Strength to my dog when on prescription medication?

    +

    Because the ingredients in our supplements are all-natural and have been formulated by vets and nutritionists, they can usually be used in conjunction with prescription medication. We would always recommend that you consult with your vet before changing your dog’s diet if your dog is on prescription medication.

    The ingredients behind Fresh-K9

    Boost your dog's hydration & recovery with Fresh-K9 Max Strength. Our supplement replenishes electrolytes, supports energy & aids recovery before or after exercise

    • Created by vets and trainers.
    • Supports hydration and recovery.
    • Natural electrolyte supplement.
    • Replenishes fluids and minerals.

    Sodium

    100mg

    Sodium is essential for proper nerve and muscle function and plays a key role in maintaining fluid and electrolyte balance. It is the main extracellular electrolyte, with its movement—regulated by the sodium-potassium pump—helping control hydration and cellular function throughout the body.

    Sodium

    Potassium

    500mg

    Potassium is the body’s main intracellular electrolyte, essential for muscle contraction, heart function, and maintaining healthy water and electrolyte balance. It also helps counteract the effects of high sodium intake, supporting normal blood pressure and overall cardiovascular health.

    Potassium

    Dextrose

    25mg

    Dextrose is a fast-acting simple sugar that provides quick energy, making it ideal for rapidly replenishing glycogen stores after physical activity or exertion.

    Dextrose

    Calcium

    500mg

    Calcium is an essential electrolyte that helps maintain balance in the body by working in tandem with phosphate—when levels of one drop, the other rises to keep equilibrium stable.

    Calcium

    Magnesium

    75mg

    Magnesium works alongside calcium to regulate proper muscle contraction and relaxation, and an imbalance between the two can lead to muscle problems that impact exercise and overall activity levels.

    Magnesium

    Glycerol

    8g

    Glycerol helps improve physical endurance by increasing exercise tolerance and allowing dogs to sustain activity for longer periods.

    Glycerol

    Citric Acid

    1.5g

    Citric acid can help reduce blood lactate levels, improving anaerobic capacity and reducing muscle fatigue, which together support better physical performance.
