Steven, I wouldn't play around with it. If she isn't eating and appears to be "drunk walking", I really am very concerned. I don't like to force feed any animal unless the vet specifically directs me to do it. With her heart condition, I don't know if forcing her to eat is the wisest thing to do. If you can't get her in today for an exam, call the vet and ask his/her advice as to what to do. They don't charge for a phone call. I would rather see you get advice from the vet that knows your dog, than someone over the internet who isn't familiar with her case. We may give you the wrong advice and it may negatively affect your dog.
