Dog probiotics are supplements that contain beneficial (good) bacteria to support your dog’s digestive system and overall health. These bacteria help maintain a balanced gut microbiome in dogs.

What probiotics do for dogs

Probiotics can help with several common health issues:

Improve digestion and help break down food

Reduce diarrhea, gas, and bloating

Support the immune system (much of it is linked to gut health)

Help after antibiotics to restore good bacteria

Improve stool quality and reduce digestive upset

May also help skin allergies and bad breath in some dog

They work by increasing the amount of beneficial bacteria in the intestines and preventing harmful bacteria from taking over.
