Hello everyone, My 8 year old Labrador, Choco, is spewing up droplets of blood like this every now and then. This happens mostly when he wakes up from sleep and is resting. Please note that this has not happened before and it’s been 2 days that we have noticed yhis happening. Even local doctors are mostly puzzled and have decided to conduct some scans for an initial diagnosis. Please let me know what you think of this.
