Quick Answers

Where can I learn more?

A probiotic is a specific strain and a specific count of live organisms. Veterinary studies are strain by strain. Ask the clinic which product they use for antibiotic-associated diarrhea. A yogurt cup has no guaranteed live-organism count, and some dogs do poorly with lactose.

How often should I take my pet to the vet?

A probiotic powder does not treat parvovirus, a foreign body, or acute hemorrhagic diarrhea. Puppies with loose stool are seen promptly, and healthy puppies are also examined every 3 to 4 weeks until about 16 weeks for fecal tests and vaccines. Adult dogs need at least a yearly exam, and dogs from about 7 years, giant breeds earlier, who are handed a probiotic for soft stool are still examined about every six months so the powder is not standing in for bloodwork. Diarrhea that lasts more than a day, blood in the stool, or a dog too tired to drink should be seen now. Whether a probiotic is even useful is a clinic decision.

How can I save money on pet care?

Use the product for the course the clinic suggested, then stop if the stool is normal. Cancel the flavored-chew subscription once the stool has stayed normal through the course the clinic suggested. A sudden bloody stool needs a same-day clinic visit. Leave the probiotic jar closed and go in.
