My dog has the diharea I took a smple to the vets and it came back positive for Giardia Antigen Thay said it was from swimming in the lake can someone give me more info on this and what it is? Thanks.
Ann Hohenhaus, DVM, DACVIM responded:
WebMD has a good description of giardia from their human digestive disorders section. Giardia is one of those diseases that can affect both humans and pets. Your pet might even get the same medication your doctor would use if you had giardiasis. If you should get sick, be sure to tell your doctor about your dog since dogs and their humans often swim in the same lakes!
