Why is a Strong Immune System Important? 

A strong immune system can fight off bacterial infections by recognising and eliminating harmful bacteria. The immune system is the body's defence mechanism against infections. And a healthy immune system can help prevent and fight off infections in pets and humans.

There are several ways to boost your pet's immune system by providing:

  • a balanced and nutritious diet
  • ensuring that they get enough exercise and rest
  • reducing stress
  • providing supplements and alternative therapies that support immune health.

Supplements that may help boost a pet's immune system will include probiotics, omega-3 fatty acids, and foods like lemon balm, ginger, turmeric and bone broth, just to mention a few.  All these ingredients are available in PetWell supplement range.

However, it's important to note that while a strong immune system can help prevent and fight off bacterial infections, it's not a foolproof defence. In some cases, even pets with strong immune systems can become sick. Additionally, some bacterial infections may require medical treatment such as antibiotics to fully eliminate the infection.

A strong immune system helps pets to:

  • Resist infections by recognising and eliminating harmful pathogens before they can cause damage to the body.
  • Recover from illness more quickly from illnesses by recognising and eliminating germs that may cause further harm.
  • Reduce the risk of chronic diseases such as cancer, by recognising and eliminating abnormal cells before they develop into tumours.
  • Improve overall health and well-being: with more energy, improved appetite, and a stronger sense of well-being.

What are the Health Risks of Bacteria for Pets?

Bacteria cause a wide range of health issues for both dogs and cats, including:

  • Gastrointestinal issues: Bacterial infections such as salmonella and E. coli cause vomiting, diarrhoea, and loss of appetite.
  • Urinary tract infections (UTIs): Bacterial infections of the urinary tract can cause frequent urination, straining to urinate, and blood in the urine.
  • Skin infections: Bacterial infections of the skin can cause redness, swelling, and itching.
  • Respiratory infections: Bacterial infections such as kennel cough and pneumonia cause coughing, sneezing, and difficulty breathing.
  • Ear infections: Bacterial infections of the ears can cause head shaking, ear scratching, and discharge from the ears.

Bacterial infections can sometimes lead to more serious health issues, especially if left untreated. For example, a severe bacterial infection can lead to sepsis, which is a potentially life-threatening condition. It's important to recognise the signs and symptoms of bacterial infections in pets and seek veterinary care promptly if you suspect that your pet may be infected.

Some bacterial infections may require medical treatment such as antibiotics to fully eliminate the infection

Recommended Dosages of Bacteria-Fighting Foods

It's important to note that the safe dosages of these foods may vary depending on your pet's individual health needs, age, and weight. It's always best to consult with a veterinarian or a pet naturopath or a pet nutritionist. This will ensure your pet's unique requirements are considered before adding any new foods or supplements to your pet's diet.

General Dosage Guidelines for Foods that Help Fight Bacterial Infections

Here are some general guidelines for safe dosages of the ten foods listed above, based on a 5kg body weight:

  1. Coconut oil: 1/2 teaspoon to 1 teaspoon per day.
  2. Garlic: 1/8 of a clove to 1/4 of a clove per day.
  3. Turmeric: 1/16 of a teaspoon to 1/8 of a teaspoon per day.
  4. Apple cider vinegar: 1/4 teaspoon to 1/2 teaspoon per day.
  5. Lemon Balm: 10-20 mg per day.
  6. Ginger: 1/16 of a teaspoon to 1/8 of a teaspoon per day.
  7. Blueberries: 1-2 blueberries per day.
  8. Oregano: 1/16 of a teaspoon to 1/8 of a teaspoon per day.
  9. Cinnamon: 1/16 of a teaspoon to 1/8 of a teaspoon per day.
  10. Fermented foods: 1/2 teaspoon to 1 teaspoon per day.

Remember that these are general guidelines and that individual pets may require different dosages based on their specific health needs. Always start with a small amount and gradually increase the dosage over time while monitoring your pet's reaction. If you notice any adverse effects, stop using the food or supplement immediately and consult with a veterinarian or a pet naturopath or pet nutritionist.

One of the safest ways to manage dosages is to provide supplements that have been professionally developed by a pet naturopath or nutritionist.

These experts are trained to understand the unique nutritional needs of pets and can help recommend supplements that are safe, effective, and tailored to reach optimal health goals.

In Summary

While the above-mentioned foods help fight bacterial infections, it's important to note that they should be used as part of a balanced and complete diet with many more whole foods.

A robust immune system helps pets resist diseases and stay healthy by protecting against harmful pathogens such as bacteria, viruses, fungi, and parasites. However, a strong immune system alone is not enough to prevent or treat some serious bacterial infections, and veterinary care and appropriate treatment are also important factors in ensuring a pet's health.
