This community is influenced by many factors including the breed of your pet, their age and the food they eat. Although a high percentage of bacteria contribute towards your pet's health, some are pathogenic and if there is an overgrowth of these bad bacteria, they can have harmful effects.
It is important to maintain the right balance between the beneficial and pathogenic bacteria. The balance can alter through stress, the use of medications and with a change in diet. Some imbalances may show as gastrointestinal discomfort and other imbalance show as allergies, diarrhoea or poor gastrointestinal health.
Bacteria have jobs to do and contributions to make, some provide energy, vitamins and help to make nutrients, such as carbohydrates, more available. Other microbes interact with the immune, endocrine, nervous system and brain.
