I am sorry to hear about your dogs bloat and glad to help.
Because Daisey is older and has had this "bloat-like" condition for 5 months, consider having a set of blood tests and abdominal x-rays taken to determined exactly what is going on internally in your dog.
Once you are able to pinpoint the exact problem then dealing with it will be much easier.
I am glad to help further and should you want to discuss this feel free to contact our office.
I hope this is somewhat helpful.
