Wow - my pup had similar bile acid results...
She's on a prescription diet too (Hills ID) What's yours on?
I really want to find a better food for her, but yet something her liver can still handle.
Mine also rings the bell to go outside and play...
I tried using two seperate leashes so she could associate one with going to potty and one to go on a walk/play. However, it didn't really work too well....and I got lazy and kept using my favorite leash.
