Trails performed by Bloodhounds are permissible evidence in court. Due to generous flews, they can fling saliva 20 feet with one shake of their head. Their enormous size, food requirements, vet bills and inherently short lifespan make them dubious companions for the average dog-lover. As is common with large dogs, they have a short lifespan of about 10 years. Bloodhounds are friendly, often very good with children.
Bloodhounds are very determined.
They are aggressive in the sense that they will want to finish trails, and that they can be hard to call off once on a track. They can be difficult to train off-leash for this reason. However, they are not generally aggressive toward other dogs or people. The pendulous skin over their ears and eyes will fall down over their eyes when they lower their head to trail, effectively blinding them. Because of this and their determination, Bloodhounds are usually run on leash for their own safety.
