Help...weigh loss, sick dog - Page 2

I know that you check for Parasites. But you said that when you give antibiotic that she gets better and then, after the treatment, she starts to have a diarrhea again. You are describing  what  would indicate to me (and I am not a vet, but just a dog man) that it is of bacterial or protozoic origin and you are touching it with the treatment but not taking complete elimination of what ever it is.
 I would suspect Giardia. It is very hard to detect in normal fecal test .In spring, 2004, a diagnostic test using ELISA technology became available. This test uses a very small fecal sample, and can be performed in 8 minutes in a veterinarian's office. It is much more accurate than a fecal examination. However no test is 100% accurate. If you come with negative results, you may want to repeat the test. OR!!! Just treat the dog with Flagyl. 
If the dog is getting better in one week then you know what it is. Sometimes it helps to use it with combination with Fenbendazole. Look you can not do this yourself. You must get all this dosed by vet. Flagyl is toxic to liver if in higher doses then necessary.
Here is good link on this:

Next would be Coccidiosis treated with sulfa. Usually given together with treatment of Giardia.
       But now we come to yet another unknown. It is possible these treatments only remove the cysts from the feces but do not kill all the Giardia in the intestine. This means even though the fecal exams after treatment may be negative, the organism is still present in the intestine. This is especially true of the older treatments. So treated animals could still be a source of infection for others..
Thus KEEP IN MIND THAT REINFECTION ARE COMMON AND MY VET RECOMMENDS TO REPEAT THE TREATMENT AFTER about 2 WEEKS. That is after more cysts are deposited and the cysts in the intestine hatch. This is a tedious process and several treatments of
all animals on the premises may be necessary.
 If that does not help then it could be some other resistant bacterial infection and different stronger antibiotic  may be necessary. You may need to find specific antibiotic for what ever culture would say it is.
Next would be allergy test.

Thank you Hans...yes I did think of that at first and she was treated twice with panacur...she had that when I purchased her as a pup argggg all to famaliar with that...and I did treat the whole household of animals and clean up everywhere,,,everyday....Im not sure thats what it is this time....ran test for that from the get go and it was clear but I said lets treat her anyway just incase....after two spaced out treatments of the pancur, retested again and still didnt show up for giardia or any parasites for that matter, I even had her tested her for lime aswell,along with numerous blood tests....I just dont know, but that does linger in my mind... Im leaning towards the pancreas cause we did also treat her with antibiotics for the small intestine bateria just incase thats what it was but shes back to the same condition as she was before treating her for that. Soooo....Im going to have her EPI tested..run another parasite test...another small intestine for bacteria again and pray something is found out this time and something works....thank you and I will mention the Flagyl this time aswell. At this point Im willing to try anything that may help....thanks

It is possible she has Irratible Bowel Disease, a friend of ours just had problems her female and what you described pretty much sums the same way as what you are describing. The vet ran all kinds of tests and couldn't find anything wrong, and gave her a shot of Vitamin B12 to increase the appetite and then it slacked off again and she just wouldn't eat. It was undiscovered for so long that the female ended up at the University Veterinary Hospital and had a biopsy done to determine what was wrong. Her liver enzymes were also out of wack. Hope this helps, good luck.

Panacur alone is not too effective. Read the link I have enclosed in the other post above.
 I also treat rather then test. "Pancrezyme" (somewhat expensive but good), for pancreatic insufficiency. If it works no expensive tests are necessary. Same for treatment for Geardia. use Flagyl w sulpha and Panacur. Forget the test. That is my experience and what my vet recommends if the tests are inconclusive. Maybe change get a second opinion from different vet.
Google the products.

I recently went thru a bout of "I do not know's" with the vet. My rott was losing weight and throwing up, stools sometimes runny then to ok then back to runny. He went on IV fluids, and they put him on Hills purina Mediclal food, combo  of the dry and wet canned, only can get at the vet.  He is doing good after that. they are guessing to much fat in the food i was feeding, and he was not processing it. My shepherds are doing great on the food, he just has developed an issue with it. I was using on him Eagle Pack, Holistice, the sardines.

What about auto immune problem?
