My dog sniffed something. Can he get Giardia from just sniffing?

How common are Giardia infections in dogs by sniffing, not actual ingestion of cysts such as drinking contaminated water?

It is possible for a dog to get infected with Giardia through that method. It is not as common as with drinking the infected water but because the cysts are small they could get in the nose and swallowed. It is not common but possible.
If Snowie has any diarrhea, vomiting or anorexia she should get checked out by her veterinarian.

    Yes, giardia is contagious. It is typically acquired by eating or sniffing the cysts from contaminated ground, or by drinking contaminated water. If the dog infected with giardia pooped on the ground, and the other dog sniffed it or ate the feces, then they could get it as well.
