Get Your Dog Care Questions Answered by Experts
Hi. Welcome to Just Answer. I'm very sorry to hear about Arto's situation. In a situation where post a neuter there is a lot of swelling and blood from the incision, these are the considerations I have.
1) Post operative minor bleeding into the tissues there that causes a hematoma to form and then it will drain due to this through the incision. This can happen with any neuter as there can be some small bleeder vessels that take longer to stop hemorrhaging.
2) A coagulation issue. Some dogs could have underlying blood clotting problems that physically make them not clot well. This could be hereditary or acquired (got into rat / mouse poison).
3) A ligature on the bigger vessel to the testicles has slipped and there is more of a significant hemorrhage from this.
In all honesty, the most common thing is the slight bleed after the surgery and a hematoma formation that isn't due to any specific ligature slip or bleeding issue. I'm hoping things go well with him.
