Did you know – the number one reason that dogs of any age or size end up at the vet relates to gut health?
You already know that the digestive systems of humans are ecosystems that are filled with good bacteria that are crucial to our well-being. So, probiotics are healthful for humans, do they work for dogs too?
Let’s check out the what, why and how – everything you want to know about probiotics to keep your pet healthy.
What are probiotics for dogs?
Probiotics are live bacteria that are useful for maintaining good gut and overall health. Probiotics for dogs work very much the same as they do for humans to eliminate gastrointestinal problems and improve gut health.
Probiotics can be administered to dogs as pills, powders, chews, or even dog food. When it reaches the gastral intestinal track where the dog’s immune system is located, it outweighs any bad bacteria to support their overall health.
A good probiotic supplement will include a multitude of different good bacteria strains to help address a wide variety of possible attacks on your pup’s immune system, be it environmental stress, dietary alterations, allergens, lifestyle changes, or health issues.
Do dogs need probiotics?
Much like with humans, it is recommended that all dogs be on probiotics, but it can be especially essential for young puppies and small dogs. When your pup is just growing, they have a particularly sensitive stomach and can experience higher levels of stress. Empirical evidence shows that it is most common for smaller dog breeds to have lifelong digestion issues.
Though the number one reason that dogs of any age or size end up at the vet relates to gut health. Since the dog’s immune system is in the G.I. track, stress that affects their gut biome will affect their overall health.
Getting your pet started on a good probiotic, no matter their breed or age, will mitigate that and help in a lot of other areas too, to keep them happy and healthy.
What are the benefits of probiotics for dogs?
The word probiotic stems from the Greek term pro bios meaning “of life,” and the essential bacteria in probiotics have so many quality-of-life benefits for dogs.
Some of the main benefits include counteracting the negative effects that stress has on your pet’s gut health and immune system. This can be stress from allergies, being left alone at home for long hours, having moved, or having an illness of any kind. It also helps in improving your pet’s ability to digest and absorb minerals, encouraging B vitamin production, assisting with weight issues, and even enhancing the oral health of your pet. It can reduce odors on your dog from their coat to their breath and gas.
- Prevention of, or faster recovery from bouts with diarrhea,
- Decrease in intestinal gas,
- Help controlling blood sugar and cholesterol levels,
- Improve immune response,
- Reduced inflammation,
- Faster recovery,
- Improved antioxidant levels.
Types of Probiotics for Dogs
Different probiotics offer specific strains of bacteria, which have been found to support and target different health issues that you are looking to address.
Generally, you want to look for a probiotic that has 5-10+ bacterial strains, with each specific strain having between 100 and 300 million colony forming units or CFUs to add up to between 500 million to 3 billion CFUs per serving, depending on the size of your dog.
You want to look for no additives, and that it’s manufactured in a GMP certified facility.
Beyond that, we recommend consulting with your veterinarian to see which types of bacteria specifically you want to be sure are included in your dog’s probiotic. What we can tell you are the different formats these probiotics come in and why you might choose one or the other.
Standardly, there are capsules, but most dogs have trouble taking pills, so there are other options. Chews are a popular choice as most dogs will think they are treats and lap them up. Powders are another great one as they can be dissolved into your dog’s food or water. You can even get dog food with a formula that includes probiotics.
