I'm sorry for asking advice again, but I'm really lost.
I posted before about my 13 year old goldendoodle reverse sneezing/coughing. We went to the vet and said she had a mild infection and got an antibiotic. It got worse and the emergency vet said it was kennel cough and was given a cough suppressant. It got WAY worse and our vet said it was pneumonia and gave a shot and oral antibiotics. It's getting worse still - she only wants to drink and it goes in water and some comes back out in slime form. She eats very little which I believe mostly comes from the medication and a sore throat because she coughs constantly. She drools a slimy fluid constantly, especially after she drinks. She sounds full of phlegm and just looks miserable. Most meds stay down, but I'm thinking some come back up in the foam.
Her X-rays showed nothing except some phlegm in her lungs. She has always been healthy and hasn't been around anything before all this began. ]
Tomorrow is Sunday and the emergency vet isn't an option (which is fine, she only glanced at my dog and said it was kennel cough so that was no help anyway) and the vets are closed. WHAT CAN I DO? I have given her electrolytes (like for babies) and all sorts of canned dog food and she turns her nose at all of them.
Monday will be the 4th vet visit in 1.5 weeks now and it is only getting worse. They keep telling me it is an infection so I have hope, but she looks and acts so bad and no medication has even helped at this point. She hasn't even slept or rested today and she was up most of the night just coughing and hacking.
Does anyone have any ideas what else this could be? Of course, I'm going to the vet again, but I'm starting to lose hope and it seems they don't know either.
Thank you, everyone. Any advice helps greatly.
