MERSJO - A premium treat for discerning pets

MERSJO is not just a treat - it is premium quality, created for dogs who deserve the best. A high meat content, carefully selected ingredients and no artificial additives make MERSJO stand out from ordinary snacks. It's the perfect choice for dog owners who value pure ingredients, functionality and a taste that dogs love.


100% NATURE

Our tasty succulent morsels are a dog's dream come true. Reach for them without fear - they are gluten-free and free of artificial colours and preservatives. Only the best from nature - for your dog's health and enjoyment.


PRODUCTION UNDER VETERINARY SUPERVISION

MERSJO treats are produced with the highest attention to quality and safety. The entire manufacturing process takes place under strict veterinary supervision, ensuring that every stage - from the selection of raw materials to the packaging of the finished product - meets the highest health standards. As a result, you can be sure that the treat on offer is completely safe and healthy for your dog, and that its composition is free from harmful substances.


PLEASANT AND USEFUL

Chewing, biting and nibbling are habits that arise from the primal instincts of our dogs. Our treats not only clean the teeth and strengthen the jaw muscles of our four-legged friends, but also reduce their feelings of anxiety in stressful situations. They are also entertaining - allowing them to occupy time spent alone. Commonly used in positive training as an ideal source of motivation.


CALCIUM LACTATE - THE KEY TO STRONG BONES

Our calcium lactate bones with dried meat combine a delicious taste with ingredients to support the skeletal system and oral hygiene.

Calcium lactate is a well-absorbed form of calcium used in supplements and functional treats. It supports the health of a dog's bones, teeth and nervous system and is particularly important in the diets of growing puppies, lactating and senior dogs.

Key benefits:

  • Strengthens bones and teeth - a key mineral ingredient for proper bone mineralisation
  • Supports the nervous and muscular systems - calcium is involved in the conduction of nerve impulses and muscle function
  • Helps prevent osteoporosis - especially in older dogs and breeds predisposed to joint problems
  • Well absorbed - calcium lactate has a high bioavailability (easily absorbed by the dog's body), better absorption than regular calcium
  • Safe nutritional supplement - often used in treats, foods and supplements as a natural source of calcium

MERSJO - A HEALTHY REWARD WITHOUT THE RISK OF GAINING WEIGHT

Our calcium bones with dried duck meat are the perfect choice for dogs at every stage of life - from puppy to senior dogs. Thanks to their high content of easily digestible animal protein (≥38%) and low fat content (≤3.5%,), they support muscle building while not overloading the digestive system.

  • For puppies - supports healthy development and provides energy in the form of an easily digestible snack
  • For adult dogs - ideal as a reward or to supplement their diet with protein and natural nutrients
  • For seniors - the soft texture and natural composition do not irritate the digestive tract
  • For dogs on elimination diets - simple, natural composition minimises the risk of allergic reactions, high nutritional value without unnecessary calories

BENEFITS OF FEEDING DUCK MEAT:

Duck meat is one of the best tolerated sources of protein, making this treat an excellent alternative for dogs with grain, gluten or poultry intolerances.

  • Protein source - duck meat is rich in high-quality protein, which is essential for tissue building and regeneration, and muscle health support
  • Vitamins and minerals - duck provides valuable vitamins such as B12, niacin (vitamin B3), and minerals including iron and zinc to support your dog's immune system.
  • Fatty acids - duck meat contains unsaturated fatty acids, which support skin and coat health and help maintain healthy joints.

COMPOSITION:

  • duck 60%

FAQ - Frequently Asked Questions

Our treats consist of 100% natural ingredients. We base them on high-quality meat (e.g., duck or beef) and natural functional additives that support your dog's health. We do not use any glues, artificial colors, preservatives, or chemicals. The meat and natural skin are held together solely through natural drying processes.

Definitely. In our offer, you will find options with specific protein sources (e.g., highly tolerated duck) as well as special treats that are 100% free from grains, gluten, sugar, and cheap fillers, making them perfect for dogs with digestive issues.

Most of our treats are suitable for dogs at every stage of life, including growing puppies and senior dogs. The addition of calcium lactate in selected products perfectly supports the development of strong bones and teeth in young dogs. However, always check the properties section on the specific product page to ensure that a given chew (e.g., due to its hardness level) will be appropriate for your dog.

Yes, that is one of their main tasks. Our dental chews have the right structure to mechanically scrape off plaque while chewing, which helps prevent tartar buildup. Long-lasting chewing is also a dog's natural way to calm down and reduce stress.

Every dog and every situation requires something different. Soft textures and small sizes are ideal for quick rewards during training (the dog eats the treat immediately and focuses on further work). On the other hand, hard sticks, bones, and chews are designed to keep the dog occupied for longer, satisfy their natural instinct to chew, and help them relax, for example, when left alone at home.

We create our treats with health in mind – they are low-fat and have a high protein content, so they do not provide the dog with empty calories. Nevertheless, they are a complementary product to the daily diet. It is good practice to ensure that the calories from treats given throughout the day do not exceed about 10% of your pet's total daily energy requirement.

Our larger packages (e.g., 500 g) are equipped with a convenient zip-lock closure. Thanks to this, the treats do not dry out and retain their full taste and aroma. We recommend using them within 14 days of first opening. Just remember to store the package in a dry and cool place.
