Antibiotics work by killing bad bacteria that cause disease and infection. However, they also kill GOOD bacteria. Always give your dog the entire dosage of medications that are prescribed.
However, talk to your veterinarian about supportive measures that can be taken during antibiotic treatment, such as a probiotic, prebiotic, or yogurt supplement.
Much to the dismay of most dog owners, it is fairly common for a dog to consume feces of other animals. While this practice is mostly safe, it does present the risk of introducing bad bacteria into your dog’s gut. If too much bad or competing bacteria are introduced, your dog’s microbiome may suffer.
Teach your dog the “leave it” and “drop it” commands and keep your yard neat in order to prevent unwanted coprophagic tendencies.
Leaky Gut Syndrome
The good bacteria that live in the intestines serve as a barrier which prevents toxins from entering the bloodstream. However, when the bacteria populations are not sufficient, gaps in the intestinal lining can form and allow food proteins to enter the bloodstream. Once these proteins have breached the intestinal wall they are attacked by the immune system. Chronic inflammation ensues, which further disrupts the gut microbiome.
