Probiotics are live beneficial bacteria that support the balance of your dog's gut microbiome. A healthy gut microbiome helps with nutrient absorption, immune regulation, and protection against harmful pathogens. Probiotics can be particularly helpful during and after antibiotic treatment, during dietary transitions, and for dogs with chronic digestive issues like intermittent soft stools or gas.
A tablespoon of plain Greek yogurt provides millions of live beneficial bacteria — there is no standardized probiotic dose for dogs, but most canine probiotic supplements provide 1–10 billion CFU (colony forming units) per day. Plain Greek yogurt and plain kefir are the most accessible whole-food sources. Dog-specific probiotic supplements contain strains selected for the canine gut. Introduce gradually to avoid digestive upset.
3.31% of daily nutrient intake
Probiotics makes up 3.31% of your dog's total daily nutritional requirements by weight.
Dogs do not develop a "probiotic deficiency" per se, but a depleted gut microbiome manifests as chronic loose stools, excessive gas, bloating, food sensitivities, and increased susceptibility to gastrointestinal infections.
Probiotics are generally very safe. Occasional mild gas or loose stools may occur when first introducing them as the gut flora adjusts. These symptoms typically resolve within a few days.
| Life Stage | Size | Min | Max | Unit | Notes |
|---|---|---|---|---|---|
| Adult | medium 10-25kg | 1000 | 10000 | million CFU | No formal requirement. Typical canine probiotic supplements provide 1–10 billion CFU. Beneficial during stress or after antibiotics. |

Prebiotics serve as food for probiotic bacteria, allowing them to multiply and establish colonies more effectively in the gut. This combination (called synbiotics) is more effective at restoring gut health than either component alone.
What this means: When supporting your dog's gut health, combine probiotic-rich foods (plain yogurt) with prebiotic-rich foods (banana, oats, pumpkin). This one-two punch feeds existing good bacteria while also introducing new beneficial strains. Especially helpful during dietary transitions or after antibiotic treatment.
