Hi I’m not sure if this is the right place to post as I’m new here so apologies if not. I have an elderly GSD (male 11) and the last couple of weeks he’s been having nose bleeds, I’ve taken him to the vet and he is unsure of what it is. He has Ulcers inside his nose which he hasn’t seen before. He’s taken swabs for bacterial or fungal and sent photos to a dermatologist to see if they recognise it. He also mentioned Lupus and that may be the way to go forward if tests come back negative. Has anyone else experience of this at all?
