Puppy has Giardia. Can my other dog get it? Should I separate them?

Updated On September 23rd, 2025

Pet's info: Dog | Rottweiler | Female | unspayed | 55 lbs

My puppy Willa has been tested postitive for Giardia via a stool sample. We have another dog who is almost 3 and have heard that she can get the Giardia simply by sharing toys and water bowl. Is this true? If so, should they have zero contact with each other until Willa is done with her medication? It would be very hard to keep them apart since they are inseparable. Some people say no, others say yes. Thank you so much for your help

Thank you for submitting your question regarding your dogs. Giardia is spread by a fecal-oral route. I typically will treat all pets in the household if one is affected. Adult dogs can be asymptomatic carriers meaning they can have and spread the disease without showing symptoms themselves. You need to scoop all the poop in the yard frequently. The toys and dishes should not be a source of infection unless they have been contaminated with feces. The dogs should avoid dog parks and similar areas where they potentially spread the infection to other pets. Good luck!
