Lionsteve asks: "We have a Yellow Lab mix. Not sure how old she is but our guess is about 8 or 9. A while back she started "snorting" when she would get excited. Sort of a asthma sort of snort. We took her to the vet and they did several test with no results. They gave her an antibiotic. No real help. It doesn't seem to bother her too much. Well a couple of weeks ago she started having bloody discharge from her nose. Just a little here and there. Just curious if someone else has seen this or might know what it is that we are dealing with. Any ideas? Thanks in advance."
