3 days ago, my 2 1/2 month golden retriever started passing worm segments in her stool. It was one segment on the first and second days and two segments in the third day.
I'm pretty sure it is tapeworm, based on description and images/videos found online. (They look exactly like this.)
Called the vet's office, then took a stool sample. Made sure one of the flat-squirmish worms were in there. Later they called saying that the result was negative.
The sample was in a large Ziploc bag (I didn't have a small one at the time). I'm suspecting they analyzed the stool sample but weren't careful enough to look around inside the bag for the worm segment.
Why was a worm exam negative when actual worm was included in stool sample?
Should I call another vet's office for a second opinion, since the puppy continues to pass these?
