The Benefits of Probiotics for Your Pet

Can you be doing more to help protect your dog or cat against digestive problems? Learn how probiotics can benefit the digestive and immune systems in your pet.

Probiotics produce short-chain fatty acids (SCFAs), which inhibit the growth and activity of harmful bacteria.

These include E. coli, Salmonella, and Clostridium perfringens, as well as providing other benefits to the intestines. 

Human studies have documented the effectiveness of certain strains in treating diarrhea, irritable bowel, and intestinal inflammation (fewer studies have been conducted on pets). 

Probiotics may help prevent urinary tract infections, and can even reduce allergic reactions by decreasing intestinal permeability and controlling inflammation.

Species with specific strains known to benefit pets include Enterococcus faecium (strain SF68) and Bacillus coagulans. Bifidobacterium animalis (strain AHC7) has been shown to reduce the time for acute diarrhea to resolve in pets. 

Certain strains of Lactobacillus acidophilus improve frequency and quality of stools in sensitive pets. Lactobacillus rhamnosus strain GG (LGG) is effective in preventing and treating diarrhea in humans, and may benefit pets as well. 

Probiotic products may contain one or several strains.

Some probiotic species require refrigeration in order to remain viable; follow label recommendations for storage. 

It’s questionable how many survive passage through stomach acid into the digestive tract, and whether they then colonize or must be continually replenished.

Many products, particularly those that are not refrigerated, contain fewer live organisms than their labels claim. 

Freeze-dried probiotics may last longer than refrigerated or other powdered products, especially if the powder is exposed to moisture (such as when the container is opened and closed). 

Probiotics in commercial foods may not survive processing or storage. Probiotic products should always provide an expiration date.

Dosing Probiotics for Pets

Probiotics are measured by colony forming units (CFUs). Few studies have been done to determine effective dosages, but these numbers are usually in the hundreds of millions or higher. 

If probiotics are being used to help with digestion, they should be taken with meals, but otherwise they may survive better if given between meals, particularly if taken with liquid that helps to dilute stomach acid and move them more quickly into the digestive tract (maybe give them after your pet takes a big drink). 

Probiotics may be given short-term or long-term.

When using products intended for pets, follow label suggestions for dosage.

When using human products, give the full dosage to dogs weighing 40 pounds or more. Reduce the dosage for smaller dogs and cats, or if you see loose stools.

Best Probiotics for Pets:

Examples of canine probiotic formulas that include strains known to benefit pets:

1. Thorne Research’s Bacillus CoagulansVet

2. Jarrow’s Pet Dophilus

3. Vetri-Science’s Vetri-Probiotic

4. Nusentia’s Probiotic Miracle

5. Purina’s Fortiflora

Several people whose pets have serious digestive disorders, including small intestinal bacterial overgrowth (SIBO), have told us of success using Primal Defense with homeostatic soil organisms, made by Garden of Life. 

Products made for humans can also be given to pets.

Yogurt and kefir with live cultures often contain lactobacillus acidophilus, and sometimes other species as well, but dosages are usually lower than those in supplements. Make sure there's no added sugar or artificial sweeteners.
