Four Leaf Rover Protect Soil Based Probiotics

Digestive and Immune System Support

Four Leaf Rover Protect is a soil based probiotic that can be given daily to aid in supporting your dogs digestive tract and immune system.

Unlike traditional probiotics, a soil based probiotic can survive changes in your dog’s gut pH and temperature levels meaning they can better colonize the gut and digestive tract with good bacteria.

Protect is veterinary formulated, ideal for everyday use and unlike many probiotics, Protect is also free from dairy and hypoallergenic.

Simply add to your dogs food once daily, suitable for fresh, wet and dry feeders.

Other benefits of PROTECT include:

  • Helps get rid of Candida and harmful yeast
  • Rich in antioxidants to support the immune system and reduce inflammation
  • Feeds beneficial bacteria in the gut for improved overall gut health
  • Helps protect and maintain brain health

Soil-based probiotics (SBOs)

Soil-based probiotics (SBOs) are species of bacteria found in soil. Unlike  Lactobacillus and Bifidobacterium, most SBOs are spore-forming. This means they can form a hard coating that protects them from heat, stomach acids and most antibiotics. In fact, many antibiotics are made from SBOs.

The SBO’s protective coating means they don’t need to be refrigerated.

And unlike most probiotics that come from dairy (like Lactobacillus and Bifidobacterium), the SBOs in PROTECT are hypoallergenic. That’s good news for dogs with dairy allergies.

Happy dog - now on 3rd tub

This product has worked wonders for Bruce our Bulldog. He would refuse food/wasn’t interested in eating/ had various tummy problems and took him to vet who just suggested chicken and rice. This wasn’t sustainable so started looking online and read the reviews for this product. Bruce now trots very happily over to his food bowl and sits excitedly waiting for dinner - I am sure this has settled him and given him back his appetite. Please don’t ever stop stocking this as Bruce and I simply can’t do without!

So far so good

Only been using this for a couple of weeks and it seems to have help his digestion. We will have to wait and see if it helps with the overgrowth of yeast that he has.
