Im so sorry. I'm very late to your thread. First of all, don't ever beat yourself up because you feel like you've failed. Like others have said you are here and that shows you want the best for Abby. Now..if the bloat look is back to normal when you see her, I would watch her carefully. All dogs tummies will expand if they drink a ton of water. I would not let her drink to the point of over fullness again. We have to stop Jake otherwise he will empty a bowl of water. I would also watch her very carefully as to how quickly she eats her food. If need be, divide her meals in half and make her go slow.
Next...as I can personally attest to.. Bully's will eat anything and everything! If you can't keep Abby in sight and make certain she has zero access to anything...crate her. It will save you lots of money and stress..not to mention Abby!
Keep an eye on her poo..look for signs that she digested something she shouldn't have.
Her ears will get better with the meds. Like you know now..water and ears..not a good match! She could be acting strange because she is hurting..and the meds could be hard on her tummy. If she has gas, you can give her a Pepcid and that will help!
Care credit is an awesome source of peace of mind. You do need to make payments but it's no interest as long as you pay it off in the time allotted. Go to their web site and read up on it.
Take a big breath and remember..This too shall pass.
