I am back form the vet. Thankfully she does not have diabetes! Her fecal was negative-which I expected, but wanted everything checked. They did a blood profile-Major SA 090, which I don't know if that is his code or a standard code so I added it if someone knows exactly what it includes. Her urinanlysis did show an excessive amount of purines which the vet said in people would be indicative of having gout. He said it is something dogs can have too, although Lulu did not show full blown symptoms, I believe I remember he did say her urine "spun down to" crystals being present (please forgive I cannot ever quote exactly so I don't want him to sound like the one saying it medically correctly--it is me). In other words, she has excessive levels of purines and cyrstals but it has not developed into stones yet. Now, I don't know that this is the cause of her weight loss--I really doubt it--I think it was discovered as a result of trying to find a reason for the weight loss which we still don't know and are going to find out the results of the blood work by the end of the week (it is slowed up because his first grandchild is to be born this week). BTW, she weighed 5lbs 5oz on his scales. I have come home and studied foods high in purines and venison is a high-purine meat, which she eats venison ZP. I now have a list of low, moderate, and high purine foods so I can work on changing her diet. This happens to be just in time because I think she is now allergic to the venison ZP! She has started scratching a lot--like she did when she was allergic to chicken. I am debating whether to go with Lam ZP which is a moderate purine meat but she may be allergic to lamb--thought she was but haven't tested out that theory completely or go with an egg (low purine/high protein food) in the AM and Acana Pacifica in the PM. Any suggestions would be appreciated.
