Hi , I'm James DVM MRCVS and would like to help you with your question
Sorry to hear about Milo
could you please tell me what tests have you done in order to determine that it is all along Kennel cough ?
is it a clear discharge ?
does it come from both nostrils ?
indeed you have done much in order to diagnose the discharge - scoping and sending samples to be cultured is the best course of action . the question remains why is he still showing discharge which points us towards other possibility (when all antibiotic effort has been exhausted).
has he ever had an Xray done on his skull ?
A problem I faced twice - especially with greyhounds / whippets and that family was a dental disease which projected towards the nasal cavity - at times the root of the tooth projects upwards into the nasal sinus and results in ongoing infections which never go away .
it even at times moves entirely up in the jaw and gets stuck in between the oral cavity in the nasal one . this is something which would be at times hard do see in endoscopy.
another thing would be a forging body which might be there as well , but you said that he has been scoped twice so they would have picked up on it by now if that was the case .
Lastly a fungal infection is another thing to consider . if a sample was sent for testing - you would have had an answer
the botXXXXX XXXXXne is the following - this nasal discharge is secondary to something else meaning that there is something causing all these repetitive bacterial infections (they are not primary) and you have yet to discover what it is .
the use of steroids and antibiotics keeps the secondary infection at bay , but once you stop them , it all comes back (am I right?!)
If it was a case of allergic irritation then the steroids would have made a huge difference , but that is not the case as I understand .
I think the major primary problem is still a mystery to us and needs further investigation . what I would start with is doing a survey of Xrys of the skull (agree to hold him down with mild sedation - perhaps your vet will allow if you wish to avid general anesthesia) .
I wouldn't want you to settle for a life of steroids. it is not environmental allergy (it'a only one nostril that acts up as you said yourself - so there is a localized problem within it ) .
another problem with need to consider is a possible parasite situated in the sinus - these are placed by flies of sheep
As you take him running in the countryside - perhaps via the farmlands , this is also something to consider .
so the plan is :
1. have an Xray done of the skull - it could be a tooth that moved to where it's not wanted , a foreign body which got lodged or else
2. consider having another endoscopy by someone else (more skilled perhaps ) and take a sample of the tissue in the nose (not just a swab)
this discharge will not end with steroids and antibiotics I can promise you that
Is there anything you wish to add or ask ?
I hope this helps
In case you have anymore questions - let me know and I shall be back ASAP to help
I can not think of any natural remedies which would amend or improve the nasal discharge. Did he not perform the endoscopy under general anesthetics ??
did your vet perform an nasal endoscopy or did he look via the same apparatus you look when looking down a dog's ear ?
I shall be awaiting your reply .
In case you have left the chat , please do not forget to rate it .
I wish you all the best (both of you).
I see, that is very good.
In that case we are left with our next step - which is the xray exam to see if anything can be located .
As I said before , the face of it being one nostril only directs us towards it being a localized problem which is coming either from the nostril or from the sinus . in both cases we need to start be doing an xray and see if there are any obviuse changes
I do hope this helps and give you a point in the right direction. in regards XXXXX XXXXX original question . sadly there is not natural remedy which will help with Milo's presenting symptoms that I know of
Do let me know if you have any further questions
please , before leaving our conversation , do not forget to rate it .
