Get Your Dog Care Questions Answered by Experts
In a situation like this, it may not be the worst situation. When a choking happens, there can be some scleral (the white part of the eye) bleeding due to the incident. I've seen this at my ER a few times when similar situations happen with two dogs and their collars. As far as the bleeding starting again, if it is from the nostril, then it could have been a clot that was there from the previous day was knocked off. As long as there isn't any lethargy, increased breathing rate or effort and the bleeding stops again - it wouldn't be overly worrying.
