      Our advanced canine rehydration supplement is designed to keep your dog hydrated and energised!

      Fresh-K9 Max Strength helps maintain hydration, especially during hot weather, after exercise or when your dog is sick. It's ideal for active pet dogs, sports dogs and all dogs needing an extra hydration boost, ensuring they remain refreshed, replenished, and ready for action.

      • Helps prevent dehydration and supports faster recovery after exercise for active dogs.
      • All-natural ingredients designed to provide energy and replenish essential electrolytes.
      • Easy to feed by mixing with water for a tasty drink.

      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

      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!

      Is there any scientific evidence that Fresh-K9 Max Strength can aid hydration and recovery?

      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.

      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.
