saliva<\/a>. Dogs and cats enjoy kissing on their owners and it only takes one click from the animal to give giardia to the owner. Animals tend to pick up dead animals and find other things when outside that could be loaded with parasites. As soon as they touch their owner, it can get inside of the owner and make them start vomiting for instance. <\/p>\n\n\n\nThe pet owner may not even wash his or her hands immediately and may scratch their heads or put their hands in their mouths. By doing this, the parasite is allowed to enter the body. Some animals don\u2019t experience symptoms until much later. Some pet owners like to share their food with their pets, such as allowing the dog to eat out of their plates. If a pet is already infected with giardia, by allowing the dog to eat out of the plate, the pet owner is becoming infected as well. <\/p>\n\n\n\n\n\n\n\r\n
