Promotes healthy skin and coat

There are many reasons why you should consider giving your dog the right nutritional supplements. One of those reasons is feeding your pet on supplements that promote healthy skin, fur and coat. These three factors determine the appearance of your dog especially the coat. This is the best way of promoting the quality of your pet’s skin and fur. Why is the case?

It is scientifically proven that the layer of your skin or even your dog’s skin has what is commonly known as the dermis. The dermis is made up of a large percentage of collagen and this is a firm foundation for any healthy skin and growth of hair. Therefore, you can enhance the general appearance of your dog’s skin by ensuring that it gets the right nutrients including collagen.

Improves digestion

Just in the same way supplements help improve digestion problems in humans such as the leaky gut, the same case is true in dogs and other pets. Dogs can benefit a lot from the supplements’ ability to boost their digestive health. In most cases, dogs experience leaky gut syndrome that subjects them to risks for other related health problems. These may include autoimmune diseases, allergies as well as behavior issues.

These digestive problems affect dogs when they are given poor diets, toxic substances, antibiotics and when they are under stress. But you can prevent all that by feeding them on nutritional supplements such as omega-3 fatty acids, glucosamine, probiotics, collagen and so on. These substances help in the repair of the gut lining, improving leaky gut and overcoming other underlying problems triggered by poor diets.

Improve appetite

If you realize that your dog has a low appetite, it is time you found a solution to that problem. A better and easy way of solving such issues is by introducing your pet to the best nutrition supplements on the market today. Adding such nutrients to their usual meals can help your dog to improve its appetite.

Reduction of inflammatory

Nutritional supplements such as omega 3 fatty acids and omega-6 work together to control inflammation. While omega-6 fatty acids increase the inflammation, omega-3 fatty acids decrease inflammation. This creates a necessary balance to maintain the dog’s immune system.

Omega-3 fatty acids are important when it comes to helping those dogs that suffer from inflammatory conditions like allergies or early atopy. These two disorders cause severe allergies leading to itching and to some extent, hair loss. In this case, you may consider keeping your pet supplemented using omega-3 fatty acids in order to control all these types of skin disorders.

Supports cognitive function

Good supplements can support the neurological or cognitive function of your dog. This is quite helpful especially in dogs that suffer from problems arising at the onset of their old age. These could be mobility issues or changes in behavior. Studies show that when dogs consume omega-3 fatty acids, they can have improved performance, cognitive function, and behavioral memory.

This can be experienced through improved mobility, recognition of all family members and many other household pets. It may also have a positive impact on certain behavior such as excessive licking and pacing around unnecessarily not mention the neuroprotective effects.

Could assist with the joint inflammation

A number of the best nutrition supplements have anti-inflammatory abilities that make them the right choice to help in the improvement of osteoporosis signs. Additionally, those supplements assist in the objective improvement to signs of lameness among dogs and objective improvement in weight-bearing scores in dogs. A good example is omega-3 fatty acid that is responsible for decreasing production of the prostaglandins ( triggers joint inflammation).

Improves heart health

Dogs that are frequently subjected to nutrition supplements are likely to experience a reduction in the development of atrial fibrillation or rather an irregular heartbeat. Some supplements can function as an anticoagulant to prevent clotting of blood. When given the recommended supplements on a regular basis, there are chances of decreasing triglyceride and cholesterol levels while maintaining healthy blood pressure. This way, your dog may be out of risks that can lead to stroke and other heart-related problems.

Reduce dry and flaky skin

When dogs experience unhealthy skin conditions, there are chances of being at risk of feeling skin irritation, allergies, itching, and bacterial infections. All these are signs of poor health resulting from lack of essential nutrients in the body. These problems can be solved by subjecting your dog to regular supplementation of nutrients to improve the health of their skins and coats.

At the same time, dietary supplements can help reduce all the effects related to the dog’s skin allergies and minimize yeast infections. A good diet can control or prevent cases of hotspots and help in the eradication of dandruff among other skin conditions.
