New to this board and it has already helped me...I have a 2yr female cavalier (Bella) who has had the "snorts" and nasal discharge from one nostril for about 6 wks. She has no other symptoms and is active and eating well etc. I have had her to the vet 3 times and her lungs are clear, heart good, no temp, no cough, skin and coat are normal and an xray of her head and nasal passages shows no obstruction or abnormalities. A blood work up was done twice- everything was in normal range except her low platlettes, which is why they wanted to repeat the first one. I have since learned on this site that the low number could be considered normal for cavaliers. So im no longer really worried about that aspect. I am worried that she has been on meds for 2wks and is no better (and no worse.) She has been on benedryl, doxycycline,previcox and zeniquin. Should I continue to be worried? She seems perfectly normal except she "snorts" when she gets up in the morning and when she is active with our other dog (who is not sick.) She does have a little bit of clear nasal discharge from one nostril only. The vet thinks it may be viral or fungal and said if these meds dont clear it up she will have to see a specialist and have more tests done. Can anyone give me any advice, suggestions or personal experience. Can a dog just have a lingering cold? Thanks in advance!!
