two different medical paths by two different vets

Hi! I need help because I'm being told multiple things by different vets. On 12/28, I took my dog to an emergency vet. She had been coughing and starting vomiting with the coughing and got very lethargic. They took x-rays and diagnosed her with pneumonia. They then prescribed her enrofloxacin (170mg/24 hours) and doxycycline (190mg/24 hours). She's about 39 lbs. They only gave me a 10-day supply, but stated in the notes: "repeat x-rays in 7 days with primary vet - if they appear normal at that time we recommend that you will continue giving antibiotics for an additional 2 weeks after resolution of radiographic evidence of pneumonia. If dog continues to cough despite resolution of her pneumonia or if the pneumonia is not getting better, consultation with an internal medicine specialist is recommended." After that, we had to travel across the country for work, so had to follow up with a new vet on 01/07, not our primary. They retook x-rays and said "x-ray slightly better, cbc looked normal, getting itraconazole." This vet told told me to cease the antibiotics and prescribed itraconazole due to potential mold exposure (not confirmed, but we are suspicious of mold in our apartment). Both vets said that the x-rays showed some of the worst pneumonia they've ever seen. During this, I've been in communication with our primary vet who stated that the antibiotics really shouldn't be discontinued. Unfortunately they can't prescribe them since they haven't had hands on her, but I should find another vet to get a second opinion. Right when my dog started the antibiotics, her energy got better and coughing and wheezing decreased. It was still there in moments, but not as much. In the 4 days off of antibiotics, I'm noticing slightly more coughing and wheezing. She still has frantic puppy zoomies, though. Help! Do I keep on the itraconazole? Do I find another local vet to get her back on the antibiotics? She's only 1 year old and I want her healthy!

Hello- and how confusing.  I could give yet another opinion here but I haven't seen your dog and don't see that it would help, as I am one vet who definitely can't legally prescribe for you.  The real question is, what can you do to ensure that you are getting the best treatment for your dog?  In my opinion the correct thing to do would be to call or revisit your current vet, take the clinical notes along with you with the correct part highlighted, explain that you are concerned and explain what you have observed over the last four days, and ask whether in light of that they might reassess you pet.

Obviously a decision may need to be made sooner rather than later, given that breathing may be compromised, so it is worth taking this into account - hopefully the vet can speak to you or at least triage (work out the priorities for) the situation as soon as possible.
