Tammy, I found an article from three days ago that seems to implicate sweet potatoes from China (which Beefeaters brand is, apparently). It doesn't sound like it's sweet potatoes, per se.
Lynne, I found this:
Symptoms of Fanconi’s syndrome (kidney failure) include:
•Increased drinking and urinating
•“Accidents” in the house
•Blood and urine tests show azotemia (high BUN and Creatinine), dilute urine, and glucose in the urine (that isn’t diabetes).
What should make you feel better is this:
Most affected dogs have recovered over time with good supportive care.
By all accounts, it sounds like you caught it early. I'm sure she'll be fine. I would imagine the dogs that are getting this have prolonged exposure to the treats.
EDIT: Here are the brands they are alerting about
So far, the brands implicated are all made in China:
•Beefeaters Sweet Potato Snacks for Dogs
•Canyon Creek Ranch Chicken Yam Good Dog Treats (FDA has issued a warning on this product)
•Drs. Foster and Smith (exact item not specified in the report)
•Dogswell Veggie Life Vitality
