Best Probiotics for Dogs (2019 Update)

Last Update: / by Chris Wilson

Probiotics are live, beneficial microorganisms (bacteria and yeasts) that help control the balance of the digestive system. They are naturally found in large numbers in our digestive tracts and those of our dogs. They are sometimes called “beneficial” or “good” bacteria as they help to keep the gut healthy, boost the immune system, produce B vitamins and enzymes and also help prevent intestinal disease. 

Apart from supporting digestive tract health, probiotics also support the balance in other areas of the body like the skin, respiratory system and vaginal tract. Probiotics can also assist with excess gas production and bloat prevention, and support intestinal regularity.

There are many different types of bacteria which have been classified as probiotics and each have different benefits. Probiotics are commonly used when dogs have been prescribed a course of antibiotics or steroids, as these mediations will naturally damage the good bacteria in the gut and slow the immune system. Other times they are used long term in dogs with chronic issues such as inflammatory bowel disease, chronic diarrhoea or dietary allergies. They can also be used short term during situations of known stress such as going to the boarding kennels, a dog show or long journeys, to help keep the digestive system regular and boost the immune system.

What to look for in probiotics for dogs

Ideally you want a product that is easy to administer and your dog will enjoy. Probiotics for dogs come in many shapes and sizes: powders, tablets, chews and liquids. Some dogs are easy to tablet, while other dogs are geniuses at avoiding them. For some dogs a powder or paste may work better. You will know which flavours will work best for your dog- does he prefer chicken, beef or fish?

You want a guaranteed analysis of how many live bacteria are present in the product and a high level delivered in each dose. You should carefully check the ingredients list to find out which specific probiotics are included, including the strain of the bacteria. There are many different types of probiotic bacteria and each one will have a different effect on the intestines. Some products may also include added fibre, pre-biotics or digestive enzymes, to improve the effects of the probiotics as well as vitamins and minerals. 

Pay careful attention to the storage instructions, as many probiotic bacteria will be easily destroyed or damaged at high temperatures. Does the product require refrigeration or kept within a certain temperature range? The use-before date is also important and should be followed.

It is important that you get value for money, nobody likes to spend hard earned cash on something that won’t work. Usually for high quality products you need to pay that bit extra, but you want to know that it is worth it.
