Sorry there was a delay...hopefully the med is there this morning and they can get her treatment started...AND she can go home!!
As for treats, they scare me. I only use RX ones and also sweet potatoes for some of my pups. I think you are wise for avoiding those things ... yes, they could have caused her problems. At least, thank God, it sounds like hers is very treatable. Some pups have ended up very sick from renal failure due to treats. Scary, scary.
