Om my goodness, YES, it's a bladder stone! How I mixed it up when DH told me after their vet visit, I don't know. Last night he corrected me, and I was both happy and upset. It appears (from my online education, which is limited) that the green beans and sweet potato treats are not good for her. They are high in oxolates, which can add to the formation?
I will be taking a detailed list of everything she eats when we pick her up Sat. morning, DH is dropping her off Friday morning as he's working nights and I won't have to take off work. I know this isn't something I want to tinker with on my own, the vet will have final say in her diet from now on. Way too easy to upset the balance of acids, oxolates, etc. She's my sunshine, and I hate to think I fed her what I thought was healthy stuff and it created this mess. May have to pull out the green bean patch too, she nibbles on it whenever she can.
From what I read the exact cause isn't determinable, some dogs are just more prone to have this upset than others, but diet is important for future issues...
this is what I found online: The exact cause of calcium oxalate bladder stones in dogs is complex and poorly understood at this time. ***Not your doing!!!!
Dogs diagnosed with calcium oxalate stones should avoid calcium supplements unless specifically advised by your veterinarian. They should not be fed high oxalate foods such as chocolate, nuts, rhubarb, beets, green beans, and spinach.
I hope Roxie comes through this now that you know what doesn't work for her. Fur babies are a constant educational experience aren't they???
