I say this straight away.. I'm a newb with my dragon.. I've only had Domino for about 3 weeks, but have just gone through an ordeal with my vet's office and Coccidilla(sp?)...
I'm in a similar situation.. I can't seem to find a vet that's knowledgeable in the proper care of Dragon. I had a bunch of fecals done, and every time they would come back as a pseudo-parasite possibly coccidilla. Check out my thread in the health section titled Pseudo-Parasites
http://www.beardeddragon.org/forums/viewtopic.php?f=6&t=123887 it basically chronicles everything I went through with my vet. Then on the 3rd fecal(all done in the same week) they told me my guy has nematodes. They wanted to put him on medicine, but b/c I didn't bring him with me they couldn't determine the proper dosage. I was skeptical of this vet since they first told me they deal with Dragons, then after the 2nd fecal they told me they don't have much experience with dragons.
Anyway.. after having gone through all this.. my best advice would be to:
1. Order your crickets from a reputable farm. Ghann's is a great place( I ordered from them after several ppl on this message board recommended them to me)
http://www.ghann.com/
I found out that many pet store feeders are loaded with parasites, due to unsanitary conditions etc..
2. (This was also recommended to me) Contact your state veterinary parasitology lab. They most likely will do a fecal for you at a reasonable cost(plus shipping costs of course) This can also be done
through your vet, and many state labs(from what I've read) encourage submissions through vet clinics.
3. Also you can check
http://www.herpvetconnection.com/ to see if there are any clinics within a reasonable driving distance
4. If you are on the East Coast you may want to contact Nicole ( I don't know her personally, but she has offered to do fecals for $5 I think, plus your shipping costs(of course)
Here's the link to her thread: Fecal Testing - Anyone Interested? *Ready To Take Fecals*

5. If you decide to stick with your vet, and they put your dragon on meds, then I would suggest contacting Tracie(Drache613) to purchase Acodophillz+ it will help to replace the good bacteria in
your dragons belly to help him with digestion etc.. especially since the meds they will most likely use are indiscriminate and kill both good & bad bacteria
I didn't end-up using any meds on my guy. He had a massive shed, and his appetite came back, and I was told just to monitor his eating, and poo'ing. As long as he has a healthy appetite, and his poo isn't runny or abnormal, then he should be able to fight it off on his own. I did order the Acidophillz+ though, as it's not a bad thing to have around, and to give your dragon periodically, even if he is healthy.
Like I said before.. I'm a newb with my dragon, and still have my training wheels on, but I feel for you, especially since I just went through a similar situation earlier this week. I'm sure someone with better info will post to you soon.. Hope your guys are feeling better soon!!! Let us know how you make out, and upadate us on how they are doing.
