Adopted the puppy last Friday, and its been healthy and active. However its stools are becoming extremely pungent, and kind of runny. I've been pretty good at crate training, and she has only gone #2 in the house a couple times early on. In those instances it wasn't so bad. However, she has been going in the yard, and lately the odor has become extremely noticable, even outside. She has also had flatulence occasionally. Now, the symptoms of Giardia in dogs is exactly this- flatulence, very foul smelling, runny stool...... although untreated it can lead to vomiting, weight loss, fever, dizziness, and ultimately death. She is not exhibiting any other symptoms now but those. On her checkout sheet from the shelter it is indeed marked positive test for Giardia 4-26-17, treatment with something that looks like (scribbled) "Panaurtmetro", and a negative re-test (aka, "cured") for it on 5-3-17. But these observations seem to suggest otherwise. I only just put 2 and 2 together this evening. Off to the vet asap of course. But my question for the forum is: How common is this in puppies, what is in your opinion the responsibility of the shelter has in this case, and how likely is it that I could catch or have caught this from being licked, stepping outside, picking up messes? Thankfully I haven't done much picking, as she has been going in the yard early on. Unfortunately for us however, its been as rainy as the Amazon here, and the yard has been cool and soggy for the entire week. Perfect breeding ground for the Giardia parasite. And the yard now has lots of puppy stools. The shelter had released the dog for adoption "on condition I would take it to the vet within a week for a checkup". This may be routine, but it also makes me wonder just how "negative" the test results were on follow-up and if the buck might have been passed on, so-to-speak. Thoughts????
