“They’re loving life... Easy to use & the dogs liked it!”
— Reece Conley, Dog Owner


“I wouldn’t call it a “health issue”, but Frank was slightly underweight at the start of the trial. Not overly noticeable, but since being on Digestive K9TM it has sorted that out and he has put on a healthy amount of weight.

His ‘Poop production’ increased, that was really noticeable. A great sign of some really good gut health! he really seemed to enjoy it in all of his food.

Naturally we started off with small doses to ease them into it, and started to notice changes after about 4 weeks.

Easy to use & the dogs liked it!”

So why is gut health in my dog important?

Gut health – what’s it all about?

  • Do you have a stressed-out dog?
  • Are they producing large, smelly stools (that you have to clean up...)?
  • Do their farts clear the room (especially when you have special guests over!)?

All of these problems can be related to poor gut health.

Probiotics, prebiotics and digestive health are buzz words in the health space right now. And although they are mentioned repeatedly in the media, what you may not realise is that a good quality digestive health supplement: a) Can benefit pets too, and b) Can help solve all kinds of issues, from stress and anxiety, to dull coat, and itchy skin, to stinky stools and smelly farts!

What are the signs of an unhealthy gut?

  • Anxiety or aggression
  • Food allergies and sensitivities
  • Constipation, Diarrhoea or Vomiting
  • Weight problems
  • Excessive gas
  • Joint issues
  • Infections
  • Itchy skin, skin conditions or a dull coat
  • Lack of energy

If your dog has any of these issues, talk to your vet to rule out any underlying diseases whilst addressing their gut health.

Why is it that digestive supplements can impact everything from behaviour to skin health?

Your dog’s gut houses 70% of their immune system! It also absorbs and digests food and nutrients, removes waste, and houses trillions of microbiota. These oodles of gut bacteria directly impact behaviour, appearance and overall health. (Who knew we were controlled by bacteria?! Bit freaky isn’t it!)

Just like with people, stress, medication, diet and lifestyle affect gut health – and the microbial balance. When the microbiome is out of whack, the rest of the system becomes compromised. Food isn’t as well digested, nutrients can’t be delivered to all the tissues, toxic compounds end up in the bloodstream, and the body’s overall health suffers.

Processed foods, chemicals, pollutants, and sources of anxiety and stress all affect your dog’s gut health. Without any support, there is nothing to restore and support the correct balance.

Is my dog’s anxiety linked to gut health?

If you have a stressed-out dog, you may have tried every remedy under the sun to help support them. Dog trainers, anxiety wraps, pheromone sprays, anti-bark collars, essential oils, even medication. But I am guessing you haven’t thought to try improving your dogs gut bacteria!

As strange as it sounds, the bacteria that live in your dog’s gut can affect their mood and behaviour.

The gut communicates with the brain via a bi-directional highway. We call this pathway the gut-brain axis.

Bacteria in the gut make chemicals that transmit to the brain via this highway. The chemical messages that land can have a big impact. Whether the effects are positive or negative depends on which bacteria are in the gut. Different bacteria make different chemicals - some calming, some triggering.

Certain gut bacteria are present in higher levels in aggressive or anxious dogs. Manipulating the microbiome can reduce anxious behaviours and cortisol (stress hormone) levels! We can positively impact our dogs’ moods and behaviours by restoring gut balance.

Dogs with severe behavioural challenges should visit their vet. Restoring gut balance will no doubt have a positive impact. And may be helpful in managing your pet’s anxiety or aggression.

“Anything wrong with the gut will likely manifest as other issues such as behavioural problems (like anxiety or aggression), excessive gas, itchy skin, a dull coat, or just a general lack of joie de vivre”.
