We have a two year old female chihuahua (currently intact) that has been having weight issues since late December / early January. Despite a very hearty appetite she stays underweight. We had blood / urine workup done about a month ago and the only definitive thing they found was a UTI. They put her on Clavamox for two weeks but still no weight gain. So they tested again and she had another (same?) UTI. Different bacteria this time and a much higher count (10,000 the first round 100,000 this round). She's now on Baytril and Cephalexin.
At this point I don't know if they have checked for stones / crystals. Called the vet this morning and haven't heard back.
In addition to our "regular" vet she's also seeing a holistic vet who specializes in NAET. She has Turtle on Standard Process Enteric Support.
Her bllodwork indicates she *might* be borderline pre-diabetic (glucose is at the highest possible OK value).
Other than eating and drinking copiously and having "off" days / times where her energy is low (and the weight issue) she is displaying no other symptoms.
Is there anything else we should be doing? Anything to help her? Anything we should be looking for / at?
Thanks so much.
