A 44-year-old man was stabbed early Sunday morning at Montavilla Park after an argument over his barking dog, police said.

Portland police officers on patrol discovered the victim shortly before 2 a.m. covered in blood on the corner of Northeast 82nd Avenue and Glisan Street.

Someone approached the man to complain about his dog barking. The two argued, then the suspect stabbed the 44-year-old in the torso, said Portland Police Bureau spokesman Sgt. Pete Simpson.

The victim was taken to the hospital with serious injuries but is expected to survive.

Police described the suspect as a short, skinny male who was last seen walking away from the park. Officers found a couple of pocket knives at the scene, Simpson said.

Both men were likely staying the night or living in the park, Simpson said.

Police contacted another man in the park to take care of the dog.
