thursday the 24th july my 12 year old small dog had to be spayed and due to tumours, had the left hand side mammary glands removed, she is eating if I hand feed her and drinking from a syringe, but she is bleeding very dark red blood from her vaginal area, today she passed a dark clot a bit bigger than a pea, is this normal? I've got follow up wednesday with vet but should I look for any symptoms due to blood loss and if so what are they, thanks x
