He told a recent council meeting he wanted greater enforcement of dogs on beaches. Cr Morris said he was responding to complaints about the behaviour of a small minority of dog owners.
"We need to take a lot more of a heavy-handed approach."
The investigation will establish whether random patrols would be a better use of animal control staff time, or if there were other priorities.
Council's animals and enforcement team leader Brent Lincoln said they received no more than a couple of complaints a week and it was mostly about dogs being allowed to rush up to people. Routine patrols on beaches would require a suitable vehicle.
Interviewed after the meeting, Cr Morris said people became upset and complained when dog owners were unsympathetic and told them to get lost. But by the time the ranger arrived, the incident was over and the owner had left the area.
He said the report would include looking at the cost implications of getting dog rangers ranging so they were not just acting on complaints.
