Pet Supplements: Prebiotics, Probiotics

Dogs and cats have short digestive tracts and complex gastrointestinal (GI) ecosystems. 

Up to 500 species of bacterial cells account for roughly 95% of all GI cells. Some are beneficial (“good bacteria”), while others are potentially pathogenic. 

Maintaining bacterial balance determines whether a pet’s digestive system is healthy and functional. When bacterial balance is disrupted, digestive upsets and loose stools often result. 

About half of all pet owners seek natural solutions to digestive problems, and one growing trend is probiotics and prebiotics: 

  • Probiotics are live bacteria supplied in treat or supplement form, which provide health benefits.
  • Prebiotics feed the good bacteria, allowing them to grow. 

“These bacteria support the immune system and its function, produce important B vitamins and take up space in the intestines,” says New York veterinarian Elizabette Cohen. “This is important because this space could be taken up by disease-causing bacteria instead of the healthy bacteria.” 

Dr. Cohen recommends Iams Prostora Max, available at veterinary offices. Her dog, Allie, accepted the supplement, even though she’s a picky eater. 

“Her problem is that she has a very sensitive digestive system and would suffer from upsets pretty often,” Dr. Cohen says. “I love it because I’m able to help support her digestive health naturally.” 

Dr. Cohen also encourages pet owners to look for fructooligosaccharides (FOS) in pet-food ingredient lists. These prebiotics, found in foods like bananas, barley, garlic, honey, rye and wheat, are fibers that feed the good bacteria to help suppress the bad bacteria.

    This is an interesting post. Calotren can be taken regularly along with plenty of fruits and vegetables. But the effects can be observed over a long period of time. It is pointless to expect the results to be obvious within a few days of taking the drug. The best thing about Calotren is that it makes fat-loss a completely natural process. You have to take healthy food and exercise a lot besides taking Calotren.

    I have found that raw certified organic dried Alfalfa Leaf Powder has had the greatest effect in our pets health. The roots of the Alfalfa plant go down to 100 feet and bring up the virgin nutrition that both you and your pet require. This is a superb way to get all the vitamins and minerals, and fibre that one needs. Check out for more info or
