I'm a norwegian vet tech student currently working part of my  internship at an animal clinic in Denmark. There are a lot of heart and  lung worms now in the summer, so we do a lot of worm tests daily. Today I  was microscoping a sample from a pug and didn't find any larvaes. But  there was something else. Without the microscope I could see a lot of  teeny tiny white "rice". I know they're not tape worm segments! Which  seems to bee the only answer people get when they find white things in  their dogs feces. I can't find anything on the internet that looks like  it. I've attached a coulple of picture I took with my phone. None of our  vets know what it is. There is nothing similar in our clinical  parasitology book. In the microscope they look kind of like a butterfly  pupa. They have spikes on their "body" and I can see a lot of, what I  believe is blood vessels. They didn't move, but one of them "spit" out  some grainy stuff. I'm so curious to find out what it is! Can you help  me? 
I only took pictures using one of the lenses, so I don't have one where you can see the spikes.
I can't identify these, but I do agree that under the microscope they aren't tapeworms.  They look like they could be maggots of some sort, and I'm curious as to whether this sample came directly from the dog or if it was collected from the yard.  If it was the latter, then it could be environmental contamination and not a parasite.  Honestly, I can't think of any intestinal parasites that look like this, but I'm not sure if there are some in Europe that I don't know.
So, all of my international veterinary readers....any clues?
