Both prebiotics and probiotics are very much essential for our dog’s health. Probiotics are the beneficial and friendly bacteria in your dog’s body. A balanced number of bacteria in your fur baby’s stomach is very crucial for combating infestations and developing a stronger immune system. On the other hand, prebiotics is some kind of soluble fiber whose main function is to serve as a portion of food to the beneficial bacteria surviving in the gastrointestinal tract of your furry buddy. And so, the presence of the best prebiotics and probiotics for dogs in his body is also very vital.

What Are The Actual Dissimilarities Between Prebiotics And Probiotics?

Probiotics: The Latin term ‘pro’ refers to ‘for,’ and ‘biotic’ stands for life. Together, the term probiotic means ‘for life’. Probiotics are some sorts of microbes dwelling in the guts of your dog. They are qualified as the ‘friendly bacteria’. Probiotics are necessary for a dog in order to resist diarrhea and other stressful condition of your fur baby.

Prebiotics: There are both soluble and insoluble substances in the body of living organisms. The insoluble substances are usually drained from the body as roughage. And the soluble substances which act as food for the friendly bacteria within the guts of your dog’s body are the prebiotics. Actually, prebiotics are simply the food for probiotics in the host body. Probiotics help in resisting diseases and help in developing a stronger immune system.

  • Weakened immune system
  • Increased constipation
