What To Look For In Dog Probiotics
Dog Probiotic Supplements are NOT all equal. Here are some of the best ingredients to look for when buying:
Lactobacillus One of the most researched family of bacteria to defend against harmful bacteria growth & boost immunity. This powerful probiotic has been thoroughly researched and has shown effectiveness.- Turmeric A powerful natural ingredient to aid digestion, support inflammation of the gut and it acts as a strong antioxidant.
- Yucca Schidigera This all-important ingredient supports digestion, serves as prebiotic fiber and helps strengthen stool.
- Black Pepper To maximize absorption of the Probiotic & Turmeric, calm the gut and support production of critical stomach acid to kill bad bacteria.
What to Look for in a Collagen Capsule
Hydrolyzed Collagen Hydrolyzation is a process by which the amino acids in collagen are broken down by heated water so they’re easier for your body to absord. This method is also the safest and avoids the use of harsh chemicals.- Hydrolyzed Collagen Hydrolyzation is a process by which the amino acids in collagen are broken down by heated water so they’re easier for your body to absord.

OVERALL GRADE
TOTAL RANKING
Pros
- Natural Ingredients
- Vet Formulated Brand
- Contains Prebiotic
Cons
- Granule Form
- Hard to Administer
- Low Probiotic Count
- Chemical Smell May Put Off Dogs
The Bottom Line
Bernie’s Perfect Poop are well known and are a probiotic that comes in a powdered/granular form. Their formula is vet-formulated and includes prebiotic as well as probiotics. In addition, they also contain beneficial enzymes to help your dog’s digestion.
However, Bernie’s Perfect Poop falls short on a few key areas. Firstly, the number of Probiotic bacteria is very low, at just 1 Billion CFU. We generally recommend 2-3 Billion CFU. In addition, they only contain 2 strains of Probiotic, which may limit the number of benefits.
Finally, because they do not come in treat/chew form, they are messier, harder to administer to dogs and the likelihood of dosing wrongly increases.
We generally recommend giving dogs a 4-6 strain probiotic in chew form, to make it easy to administer while offering a potent dose of Probiotics.

Pros
- 6 Strains of Probiotic

Cons
- 1 Billion CFU
- Powder Form
The Bottom Line
The Probiotic Miracle from Nusentia is well-received for supporting digestive health and overall wellness in dogs and cats. It uses a formula that includes six thoroughly researched strains of beneficial bacteria. Additionally, the product is sugar-free, soy-free, wheat-free, and byproduct free.
However, there are some drawbacks noted by users. Some reviews mention that the product can be a bit pricey compared to other powder based supplements. There is also the occasional report of pets not responding to the supplement as well as the inconvenience of having it in powder form versus a chewable treat.

Cons
- Not Flavoured
- Poor Value For Money
- Low CFU Count
- Low CFU Count
The Bottom Line
Last on our list are Only Natural Pet's probiotic product. This product fell short on quite a few reasons, firstly, they are not flavoured, which in our experience can lead to dogs not wanting to take them. Secondly and more importantly, there is no Turmeric nor a high CFU count, which generally results in poor results. Beyond that, there is no moneyback guarantee and so there is likely a lower chance of being refunded if no improvement is seen.

Pros
- Cheaper Option

Cons
- No Lactobacillus
- No Bifidobacterium
- Lower Probiotic Dose
The Bottom Line
PawMedica Probiotics for Dogs is a well-rounded formula for enhancing digestive health in dogs. It includes a combination of probiotics and digestive enzymes that work together to support gut health. However, it does not include certain strains which have become very popular such as the Bifidobacterium and Lactobacillus families of bacteria.
In addition, it appears to have a lower dose of Probiotic (CFU Count) than some other competitors.
Customers reviewed it well for its value for money and it may serve well as a cheaper option.
