Probiotics have enjoyed a surge in popularity on the human nutritional market - and now it's no surprise that pet owners are wanting to enjoy the benefits for their four-legged friends Richard Allport tells you everything you need to know. 

Friendly bacteria?

Do bacteria have feelings? It does sound unlikely, yet we regularly hear about ‘friendly’ bacteria. I suspect that the bacteria in question don’t really choose us as friends, but there is no doubt that some bacteria (known as probiotics) are indeed not just friendly but actually helpful to us and to our pets.

Probiotics are the beneficial bacteria that live in the mouth and digestive tract. They help our digestion, our oral health and our immune systems – and that of our pets in exactly the same manner. Probiotics produce short-chain fatty acids (SCFAs), which reduce the growth and activity of harmful bacteria, such as E. coli and Salmonella, as well as providing other benefits to the intestines. They can help in treating diarrhoea, irritable bowel syndrome and other types of intestinal inflammation. Probiotics may help prevent urinary tract infections, and can even reduce allergic reactions. They can help with the health of the teeth and gums by reducing the number of harmful bacteria in the mouth that cause gingivitis and periodontal disease.

The gut is often called ‘the second brain’, because it has a rich and complex nerve supply which is closely connected with the brain itself. There is constant communication between these two ‘brains’ and recent studies in animals show that changes in the gut bacteria seem to make mice less anxious and also affect levels of the stress hormone cortisol. It appears very likely that this applies to all pets and to humans too.

Choosing this right probiotic

Probiotics are good for the digestive and immune system, for gums, for the urinary tract and for anxiety and stress, but how do you choose a suitable probiotic product for your cat or dog?

  • Look for a product that contains a prebiotic as well as a probiotic. A prebiotic is a form of fibre that the probiotic bacteria can feed on and so multiply more quickly, meaning they will work better and faster. The most common prebiotics used are known as fructo oligosaccharides.

  • Choose a product that contains more than one probiotic. Different probiotics colonise in different parts of the digestive tract, so it is logical to give your pet a formulation with two or more strains. There is much discussion amongst experts as to which probiotics are most useful, but the general consensus is that Enterococcus faecium, Bifidobacterium species and some Lactobacillus species are the ‘go to’ probiotics for pets.

  • Give your pet probiotics at any time of stress (such as before and after surgery or going into kennels and catteries), whenever there is diarrhoea or any other digestive upset, at times of urinary tract infection and whenever antibiotics are being taken, as these can adversely affect the normal balance of bacteria in the bowels. It has also been shown that you should give probiotics during a course of antibiotics, not just after.

  • When giving probiotics, administer daily, with food, and I normally recommend giving a course for at least one month. For pets with known persistent digestive problems, allergies or other immune system disease, or those with chronic anxiety conditions, it makes sense to give probiotics daily, permanently (this is perfectly safe). Some breeds of dogs are prone to digestive problems (such as German Shepherd Dogs), some are prone to allergic skin disease (such as West Highland White Terriers) and some are prone to gum and dental disease (such as Yorkshire Terriers and most very small breeds of dogs). These breeds may also benefit from long term probiotic supplements to help keep these conditions at bay. For pets that are normally healthy, give a one month course as and when the need arises as described above.

So while bacteria can be friends or foes, we should definitely give our pets the benefits of the friendly ones whenever they need them. Whether it’s their digestive, dental or immune health, or even their anxiety and stress levels, probiotics could be a real help.
