I took my boy to the vet because his nose was bleeding and he was only breathing from one nostril. The side with the blood also had his eye weepy with the white cleaning fluid constantly and was swollen. The vet said to try and suction his nostril out before coming to see if something was stuck and oddly this made his mouth bleed at the base of his front teeth. While at the vet she took a sample of this odd blood and tissue and looked under the microscope for cancer but only saw signs of bacterial infection. He's on antibiotic and is whistling a lot less (lost his appetite from the antibiotic unfortunately), but his nose and mouth started bleeding again today (5 days on antibiotic). his gums look like they have that weird bloody tissue stuck to them or maybe growing on them. Could this be something stuck in his gums that just caused a sinus infection or is this his teeth growing the wrong direction? he has a checkup on Thursday but I want to be prepared in case the vet wants to put him down.
