I wanted to come back and post a follow-up in case anyone is searching later...
I kept going back and forth about calling the vet for a couple of reasons. One is that I felt like I was overreacting, and an other is that I have never really settled on one particular place. But I haven't had time lately to cut her hair (poodle) so when I called to make an appointment they saw she was overdue on her rabies vaccine and wouldn't give me an appointment. I called a brand new vet clinic near my house and made an appt.
I had planned on having an exam and heartworm test, plus a 3yr rabies, but when the vet heard her symptoms she suggested a "senior panel" series of blood tests as well as urine screen. The poor baby has a "very bad" UTI, her sodium is elevated, and white blood cells are down (which seems weird to me if she has an infection...shouldn't white cells be up?)
Anyway, this is what I think caused it...6mos ago I moved pretty far outside of town. Buying raw food was going to be tricky bc of being so far away from the only store around that sells it, plus keeping it cold til I got home. So I ordered a couple cases of canned food and when that was gone I went back to kibble. I had her on Nature's Variety Instinct canned food and the kibble was their Raw Boost. Top of the line stuff, right? Guess it doesn't matter bc it's not species-appropriate.
She's on an antibiotic for the UTI and since getting her back on raw last week she's not chugging water like before. Later this week I will take her back to see if her sodium came down any.
All told, it will cost me well over $300 to get her back to good health. So for anyone searching on these boards for a brand of dog food, if you see this, take note: Even he best kibble or canned food is not nearly as good as raw, and if you think you are saving money, you're not bc you will end up spending it at the vet anyway!
On the bright side, I love the new vet and will stick with her from here on out. She didn't even blink when I said I was going back to raw food!
