Couching progressing

[PPointer]

I have a Portuguese pointer , that was doing a daily swimming in a pond for 3 month. She started couching , hacking here and there and then it progresses to at night time. she was put on prednisone and amoxicillin.
couch stopped 3 days into it for 2 days and then started back up. ran thru the medications and about a week after finishing them couch got worse. Did x rays they show donut rings in the lungs. So tried doing nebulizer with albuterol did nothing for 3 weeks 3 times a day. Did another dose of prednisone double the dose of last time a week in to it and she is getting worse. Started amoxicillin and Enrofloxacin couch stopped 3 days into the medication and she gained a ton of energy. After the 2 weeks of antibiotics a week later couching got bad again.
I started her on  Theophylline 200 mg morning and 200 night . coughing suppressed most of the time. I started to reduce her dose because diarrhea to 200 mg just at night. she started a really wet couch watery eyes and watery nose. I'm at a loss.

My goodness....You have gone above & beyond for your girl......Bless you!!!  One of mine had sudden Pneumonia not long ago....Like overnight.....Just a few coughs that I really wasn't concerned about.....Was quite surprised when the chest xray showed lungs full of fluid.....

On hers, the xray showed the whole lung area to be clouded WHITE.....It was based on that view....

She was treated with an injectable broad spectrum antibiotic that lasts for 2 weeks, but stays in the system longer...It's fairly new....I'll have to go look up the name......"Convenia".  I'm worried about this new drug however, only for one reason......As with any medication, a reaction can occur......With oral pills, you can stop giving them.....With these long term injectable ones, any reaction and your basically screwed! That worries me!

This med DID clear up her Pneumonia though.....I'm sorry I cannot be of more help to you and your dog...Seems that your Vet is doing a very, good job!!!! I DO hope you get to the bottom of this AND that it's treatable.....

I'll we watching for updates.....My Blessings to you and your girl.....Your in my prayers.......Karla

The test came back negative for Blastomycosis. So I'm dealing with Pneumonia or tumor or cancer. I'm going for Pneumonia any info on what drugs would work would be helpful . I thinking of doing a month of antibiotics and then doing xrays again to see the results.

Gave her Benadryl 25mg , at noon fever was 103.5 by 3:30 it was 103.9
She can’t open mouth or chew , something hurts in there. Little or no drinking
Took her to Blaine.
Abscess behind the left eye

8pm temp was 101 and looking better, no coughing at night, but wet coughing
Feb 3
Temp 100.9 looks good and is chewing and opening her mouth.
Went to Blue Pear in Eden Prairie ( vet specialist)
Saw Jill Lurye
Did xrays and they show a mass forming on the left side lung , the lungs also look more restricted then the original xray 2 month ago.
They wanted to get a sample of the lung and do test.
Mind you my bill is $450 and this test will tell me ? if it is a tumor or cancer I don’t need to know, I put enough antibiotics through her if it was bacterial it should have went away. If it Blastomycosis we can try and treat that, so we did  a urine sample and sent it in , should know in 2 days. My gut just say try the fungus medication, can’t hurt. Very disappointed in blue pearl for being out of touch of what test cost, and going by a script of what to do next and not looking at the full picture.

Since Antibiotics don't seem to be helping, I'd lean towards "Lung Worms" which would apply to your dogs lifestyle OR a Lung Fungal infection.....Give us some updates, please........Karla

Donut rings in the lungs?  Did your Vet explain that?  
Swimming in a pond?  Parasite or bacteria of  some sort?
Tests for TBD done?

Welcome.....How old is this dog? Is she fully vaccinated? Has your Vet done a complete blood panel looking for any clues? How about a fecal sample? Has that been done?  Is she running a fever? More information is needed.....Thanks, Karla
