Decoding the Gut-Brain Axis:


How Your Pet’s Microbiome Fuels Total Wellness

image

Think of it as a bustling, hidden ecosystem of trillions of tiny living helpers (good bacteria!) residing mainly in their gut, but also in their skin and their mouth. This unique community is essential for holistic dog care, working 24/7 like an inner command center to keep the dog healthy and thriving.

It is like a well-tuned orchestra for your dog's body! It's crucial for smooth digestion, properly absorbing nutrients, maintaining a strong immune system, and even influencing their mood and energy levels through the gut-brain axis. When it's in harmony, the dogs feel their best.

Yes, it's fascinating science! The gut and brain are constantly "talking" via the Gut-Brain Axis. It produces beneficial compounds and sends positive signals that can contribute to a more stable mood, sharper focus, and a calmer demeanor in the dog.

It's all connected! The gut-skin axis shows that it helps to regulate the immune system and normal inflammatory responses. This can translate to healthier, more resilient skin and can support a balanced response to common allergens, promoting greater comfort.

Dog eats it fine, waiting to see impact

Requesting a review this early is problematic, but I'll try. My dog eats the supplement fine in his food. I have not noticed any changes in his breath or anything else. I am waiting to see. He recently was treated for an Ulcer and I hope this will help keep it from happening again, but I fear the opposite. It's too early to tell. In the meantime, he is status quo and eating the supplement well.

Easy to use

She hesitated to eat her food at first with this supplement added, but got used to it and now won't eat without it. Her skin is healthier, and she has visibly more energy. Great value and quality product. What I like most is how easy it is to put this in the food and homemade treats.

Good option instead of multiple supplements

I’ve tried so many products for my buddy, with mixed results. Plentum is the first one that seems to work for now. It's been 1 month we are using this suppleemnt. Within a month, I saw a few changes in him, he is more cheerfull, has fresh breath, and his poops are more consistent. For about a dollar a day, it’s worth every penny compared to buying multiple supplements.
