#2: Animigo Digestive Probiotics
Animigo Probiotics are formulated to support digestive health in dogs, with ingredients aimed at promoting gut wellness. While not specifically designed for itch relief, customers have shared mixed results, with some seeing benefits, but it’s important to note that outcomes can vary depending on the individual dog’s needs.

#3: NutriPaw
NutriPaw is a highly popular probiotic chew in the UK. When you read the reviews on Amazon and Trustpilot, it’s hard to miss all the 1-star reviews which claim that their recent formula change has led to disappointing results. Many recent users have reported that it no longer delivers the same benefits. Despite this, we’ve chosen to keep it on the list in the hope that NutriPaw will eventually revert to their original, more successful formula. However, at this time, it’s clear that the product is not living up to its past reputation.
Pros
If NutriPaw were to switch back to their original formula, the product could return to being highly effective for gut health and itch relief, as it was widely praised before the formula change.
Contains a blend of probiotics that promote overall gut health and digestion.
Cons
Effectiveness has reportedly declined since the formula change.
Contains 2 billion CFU per dose.
The refund process can be slow and complicated for dissatisfied customers.
Trustpilot ratings have gone down over time, with current score at only 4.0 out of 5.
Why Heating Matters
Did you know that reportedly most dog probiotics are made in the same factories? This is something most pet owners aren’t aware of, but it matters because of how the probiotics are processed. Most brands heat their chews above 40°C, which can kill the beneficial bacteria, making the product ineffective. Ideally, probiotic chews should never be heated above 40°C to ensure the good bacteria survive. This is why choosing the right brand with proper manufacturing processes is key to seeing results.
Our Verdict
Choosing the right probiotic for your dog can be overwhelming, especially with hundreds of options available on the market. Most of these products are average at best, often offering similar formulations without standing out in terms of quality or effectiveness. That’s why we’ve narrowed it down to the clear winner and one notable mention. DogSuppy Itch Relief probiotic chews takes the top spot with its 3 billion CFU per chew and glowing reviews on Trustpilot, and their service including a free next-day delivery and 60 day money-back guarantee. While it may not be as well-known in the UK yet, DogSuppy is a leading brand in Europe and recently won an award for “Best Product of the Year 2024 – 2025” by the Dutch Consumers’ Association.
FAQ’s
Is there anything specific I should watch for when introducing probiotics into my dog’s diet?
When adding probiotics to your dog’s diet for the first time, it’s a good idea to keep an eye on a few things. Your dog might have mild digestive changes, like loose stools or gas, as their system adjusts, but this should settle down within a week. Start with a smaller dose and gradually work up to the full amount to ease the transition. Also, watch for any allergic reactions, such as itching or digestive discomfort, just to make sure everything is going smoothly. It’s always helpful to observe your dog’s behavior and overall health during this period to see if the probiotics are making a positive difference.
How long does it usually take for probiotics to show results in dogs?
It depends on the state of the gut health of your dogs and other factors, but usually it takes around 2 to 3 months.
What is CFU in probiotics, and how many strains should my dog’s supplement have?
CFU stands for Colony Forming Units, which refers to the number of live and active bacteria in the probiotic supplement. For dogs, a higher CFU count often leads to better results.
