The immune system in dogs: Why it is so important – and how you can strengthen it

Whether it's recurring infections, skin problems, or sluggish digestion, a weakened immune system is often the cause. It not only protects your dog from pathogens but also keeps his entire body in balance.

In this article, you'll learn which dogs are particularly susceptible, what weakens the immune system, and how you can strengthen it naturally.

Which dogs have a sensitive immune system?

Not all dogs are equally resilient. Certain life phases or circumstances make the body more vulnerable—special support is worthwhile in these cases:

• Puppies: Their immune systems are still developing. They are particularly susceptible to infections after weaning.
• Seniors: With age, many bodily functions slow down – including the immune system.
• Dogs with chronic illnesses: If a dog suffers from skin problems, allergies or gastrointestinal disorders, its immune system is often permanently challenged.
• Dogs in stressful situations: Travel, moving, vet visits or new pack members can put a strain on the immune system.
• Animal welfare dogs: Often weakened by stress, inadequate nutrition or previous injuries from abroad.

What weakens your dog's immune system?

Various factors can impair your dog's immune system – often unnoticed in everyday life:

• One-sided or poor diet
• Too many chemical exposures (e.g. medications, deworming treatments, vaccinations at short intervals)
• Lack of exercise or under-stimulation
• Constant stress or lack of sleep
• Infections, parasites or environmental toxins

If the body is permanently in an “alarm state,” there is no energy left for effective immune defense – diseases then have an easy time.

How to strengthen your immune system

The good news: You can do a lot to support your dog – often with simple, natural means.

Healthy, balanced diet: High-quality nutrients are the foundation of any immune function. Make sure your dog is fed good quality food, ideally supplemented with natural nutrients.

Exercise and fresh air: Daily walks, play, and nose work not only promote circulation but also activate the lymphatic system.

Promote gut health: Approximately 70% of the immune system is located in the gut. A healthy gut flora is crucial – for example, through probiotics, fiber, and support like our Stomach & Gut Buddy .

Respect rest periods: Good sleep and a safe place to retreat are just as important as exercise.

Targeted supplementation: With natural active ingredients such as echinacea, sea buckthorn or rosehip, you can specifically activate your body's own defenses – for example with our Immune Booster .

Conclusion

A strong immune system is key to a long, healthy dog ​​life. Especially during stressful phases of life, it's worth taking a closer look at nutrition, intestinal health, exercise, and natural support.
