Boost Your Dog’s Immune System This Autumn

Boost Your Dog’s Immune System This Autumn

As the weather turns colder and wetter, dogs spend more time indoors, meet more germs, and may get less exercise. These seasonal changes can weaken the immune system, leaving dogs more vulnerable to coughs, sniffles, skin flare-ups, or digestive issues.

For dogs that are older, recovering from illness, or naturally more sensitive, autumn is the perfect time to give their immune system a boost.

Signs Your Dog May Need Immune Support

  • Frequent sniffles, coughs, or infections
  • Slow recovery from illness or injury
  • Dull coat or flaky skin
  • Low energy, lethargy, or “off” behaviour
  • Digestive upset (loose stools, poor appetite)

Immune-Boosting Superfoods for Dogs

Mushrooms are packed with beta-glucans — natural compounds that activate immune cells, improve recovery, and help protect against infection.

Proflax Supreme Shrooms is a unique blend of five organic mushrooms:

  • Reishi and Maitake: Promote heart and liver health
  • Lion’s Mane: Supports brain and cognitive function
  • Cordyceps: Boosts energy and vitality
  • Coriolus: Aids digestion and respiratory health

Together, they build daily resilience, helping your dog fight off seasonal bugs and feel stronger every day.

Lifestyle Tips to Keep Immunity Strong

  1. Keep Your Dog Moving
    Exercise helps keep the lymphatic system healthy, which is key for fighting infections. Even short walks in wet weather make a difference.
  2. Maintain a Consistent Routine
    Stress can lower immunity. A steady schedule for meals, walks, and playtime keeps your dog feeling secure.
  3. Support Gut Health
    70% of the immune system lives in the gut. High-quality food and probiotics (or blends like Omega Vital) help maintain a healthy microbiome.
  4. Keep Things Clean — But Not Too Clean
    Regularly wash bedding and wipe muddy paws, but allow your dog exposure to normal outdoor microbes to help build natural resistance.
