Thank you for your response, Ajay has been treated for lungworm too and hasn't travelled anywhere to have caught the heartworm diesease. I saw my vet last night and he has booked Ajay in for more X-rays and a bronchoscopy to take a sample to see if there are any eosinophils present that would indicate an allegic response (I cant remember the full name of the condition) and then perscribe some steriods accordingly.
Thank you for advice
The original bronchoscopy was done to check for a foreign body as this was one of the possible causes of Ajay's cough. The sample taken at the time did show a certain type of bacteria to be present that is more commonly associated with the presence of a foreign - I can't remeber the name of the bacteria though sorry, but my vet said last night the sample didn't show the presence of eosinophils. So they then went on do perform a CT scan hoping to find a foreign body present that Ajay might have inhaled but not such luck. The next step was to put Ajay on a longer course of antibiotics and see how he was, the cough lessened but didn't completely go, I suggested trying a different type of antibiotics like in humans to see if this would help. Ajay had a two week course of these which seemed to be helping and the cough had almost gone but then 3/4 days before the course finished the cough came abck and got worse. When I went last night my vet suggested the above procedures with the reasoning that the antibiotics could have cleared the infection but there could be an underlying allergic reaction that is the reason behind the cough hence Ajay is still coughing, so if we do this next lot of procedures (which is happening tomorrow) and these eosinphils are present Ajay can then be put on the steriods and hopefully this will solve the problem. My concern is that we have been down this road before and others and got no definative answers what happens if we don't get answer from this? My vets didn't want to put Ajay on the steriods first as he said this would be treating him blind! I understand this but if the results come back with no really answer he will still probably try the steriod route.
Its a bit of a puzzel really and quite an expensive one!
Ok thank you I'll keep you posted on what happens with Ajay
just a quick up date on Ajay he had all his procedures done yesterday and is home and well
My vet went through the x-rays last night and showed me the difference between these and the last set and his lungs do look clearer which is good, the bronchoscope pictures also showed not as much puss present they have sent a sample off which should be back Monday. However my vet seems to think it might not show much and that Ajay is on the mend as there is not evidence of an allergic reaction, so he is on a 3 week course of antibiotics and we have to go back in 4 weeks to see how he's doing, hopefully for the last time.
