Do Dogs Need Probiotics?
August 15, 2025
Just like in humans, a dog’s gut has many responsibilities to keep them fit and healthy. At times, it needs a little support, which is where probiotics come in. In this post, we explore the world of dog probiotics, answering queries around their effectiveness, responsibilities, and necessity for your pooch’s health. Keep reading to find out all there is to know about dog probiotics.
What Are Probiotics for Dogs?
Probiotics are a collection of microorganisms that can be given to dogs to support their gut health. Probiotics work with your dog’s existing microbes to help them achieve the many tasks they must undertake. This ranges from digesting food to regulating bowel movements. When your dog’s natural microbiome is compromised, it may struggle to fulfil its usual duties. This is where probiotics can become especially helpful.
Can Dogs Take Probiotics?
It’s important to note that human probiotics and dog probiotics are two different things. According to PetMD, it is generally safe for dogs to take human probiotics, but failing to give them pet-specific supplements may result in fewer benefits. So, the answer is yes. Dogs can take probiotics, provided they’re specifically designed for dog consumption.
Signs Your Dog Needs Probiotics
Probiotics are sometimes necessary for your dog. While some dogs can go their entire lives without needing them, others might depend on them to function properly. If you’re wondering whether your dog will benefit from probiotics, we’ve compiled some tell-tale signs that something is up.
Gastroenteritis
While gastroenteritis can be caused by a variety of triggers, some symptoms, like diarrhoea and vomiting, can be a sign that the gut’s microbiome is imbalanced, calling on the need for probiotics. Using probiotics can help reintroduce the good bacteria that your dog has lost as a result of their vomiting.
Bad Smells
Passing gas is normal for dogs, but if you’re noticing particularly foul smells from their behind, something might be up on the inside.
Odd Noises
Stomachs make all sorts of odd noises. But, sometimes, excessive tones coming from your dog’s belly might indicate some discomfort. Not only can this be quite discomforting to hear, but it can also make your dog feel uncomfortable on the inside.
Loss of Appetite
Your dog’s stomach is intrinsically linked to its appetite. If you notice a sudden loss of appetite for no apparent reason, your dog’s stomach could be suffering.
Types of Dog Probiotics
Probiotics can be given to your dog in multiple forms. Here are some of the common types available:
Pills and Supplements
To add a temporary boost of probiotics to your dog’s diet, pills are one of the least invasive methods. They can be added to your existing dog food or be stealthily delivered alongside a treat.
Enhanced Dog Food and Treats
Some types of dog food or treats can be found with probiotics added in. Take our functional dog treats, for example. Our Support+ range is packed full of probiotics to improve digestion, as well as extras like glucosamine for joint health.
Liquid
You can sometimes find probiotics in a liquid form, which can be easily doused over dry or wet dog food. This makes them easier for your dog to swallow and more difficult for them to detect and reject.
Probiotics vs Prebiotics: What’s the Difference?
Although they sound similar, ‘probiotics’ and ‘prebiotics’ are two different things.
· Probiotics are the bacteria that help balance a dog’s gut.
· Prebiotics are the food source for probiotics.
To put it simply, a probiotic is a living organism, and a prebiotic is what that organism lives off. Dogs can’t directly digest prebiotics, but the healthy bacteria in probiotics live off them. So, it’s important to strike a balance between the two.
Should I Give My Dog Probiotics Every Day?
Exactly how much probiotics your dog needs will largely depend on their gut health and their physical size. Some dogs will require daily doses along with their usual course of food, while others may only need a short-term fix when issues flare up. Bigger dogs will typically have a higher gut capacity, and therefore, more bacteria. Their metabolic rate may also be higher than that of smaller breeds. As a result, they could require a larger probiotic dose. The best way to get a firm answer on this query is to speak to your vet. With your dog’s medical history in mind, they’ll provide a much more personalised answer to this question.
