2. For your dog's healthy skin and coat
Your dog's skin and coat are a clear indicator of their health. Most pets that have a dietary deficiency or suffer from an illness tend to have poor, dull fur, which is one of the first warning signs of a possible health problem.

However, there are also some dogs that simply have poorer fur and many others, especially in the case of some breeds such as Bulldogs or Pugs, which tend to have skin problems because their skin is simply very sensitive.
No matter what the cause, Dermakun is the best solution for dogs that experience itching, redness or inflammation of the skin or a dull and poor quality coat. It is also recommended during shedding seasons and is a basic supplement that can be given at any age to prevent the appearance of skin conditions in your dog.
3. To help your dog gain weight
Dog food supplements can also be used as a complement to their diet to help them gain weight.
You can find many options suitable for puppies that have a hard time gaining weight or for dogs that have lost weight after suffering from an illness. It is also common to give these types of supplements to rescued dogs with severe malnutrition.
It is important to keep in mind that these types of supplements should always be complemented with a rich, healthy, and abundant diet. They are not substitutes for your pet's daily rations; they are simply a support that will help them gain the weight they need more quickly.
4. Kidney Failure in Dogs
If your dog has kidney failure or any other problem related to the health of his liver and kidneys, he will likely urinate more frequently. This causes him to eliminate large amounts of water-soluble vitamins, so he will need extra through supplementation.To help him recover, it is also advisable to provide him with large doses of B vitamins and vitamin C through his diet and/or supplements; the main ones involved in the proper functioning of the renal system.
5. Helping Your Puppy Grow
Puppies may need an extra supply of vitamins to help them grow healthy and strong. Therefore, it is common to use supplementation during the early stages of their lives as a complement to a healthy and balanced diet.
The best option is to have vitamin complexes rich in all the essential vitamins for dogs complemented with food specifically formulated for puppies or a homemade menu designed by a specialist.
6. Adult Dogs
Taking care of our pets' health is a lifelong task. As your dog grows older, he or she will need extra care to address the new needs that will arise over the years.

The or we present Elderkun, our natural supplement specially designed for dogs from 5 or 7 years of age. It has a formulation designed to help you maintain the neuronal health of your furry companion and prevent brain degeneration.

8. Joints

Older dogs, those who are a few pounds overweight, or those who are very active may end up suffering from joint pain. This is also very common in large dog breeds with very rapid growth such as German Shepherds or Golden Retrievers.
Joint problems are very painful for dogs and can also affect their ability to run and jump, and in advanced cases, even walk; something that ends up causing them a lot of discomfort. Therefore, in these cases, it is essential to have good prevention.
We recommend opting for Arthrokun, a natural supplement that can be given at any age and is especially recommended for reducing joint discomfort in your dog and preventing its appearance.
9. Stress, anxiety, and mental health
Stress and anxiety can have a huge impact on your dog's health, both mentally and physically. Periods such as moving, socializing with new family members, or the loss of a companion can take their toll on your furry friend's well-being.
Poor mental health in dogs can affect their physical state, causing them to lose their appetite or even lower their defenses; leaving them vulnerable to possible diseases.

To increase the defenses of your furry companion we propose Immunokun, a recommended supplement For puppies or senior animals, obese dogs, or those going through a stressful period. This supplement is the support they need to take care of their immune system while their mental health recovers with your care and support.
If your pet is unlucky enough to have epileptic seizures, Immunokun can also help. Check out this post on epileptic seizures in dogs and how to treat them.

These essential oils are usually found in the diet or in supplements specially designed to care for a dog's coat and skin, but they can also be found for sale in capsules.
5. How do I give my dog vitamins or supplements?
The best way to give your dog vitamins or supplements is to introduce them naturally into their daily diet. Our pets usually hate taking pills, and they don't usually like drops either because of their unpleasant taste. Therefore, it's important to explore other alternatives.

All the vitamins your dog needs can be found in natural foods: sardines are rich in vitamin B, eggs in A, D and B12, cheese in vitamin A and honey in vitamins B and C, etc. However, it is very difficult to design a homemade diet that really provides your dog with everything it needs in the right doses.
