A row over dogs using a local park in Hobart has hit a new low, with one resident saying human poo has been used to deter dog owners from the area, prompting a police investigation.

The drama over whether dogs should be allowed access to the park in Lenah Valley, in Hobart's northern suburbs, had been "going on for some time", a resident who did not want to be named told ABC Hobart.

The fenced Girrabong Play Area, on the corner of Girrabong and Firth roads, features picnic tables and recreational facilities and dogs are permitted off the lead.

The situation escalated to include a leaflet drop asking for "photos, footage and statutory declarations" as evidence of who is responsible for faecal matter being distributed in the area, including in the driveways of nearby houses.

A Lenah Valley resident, who did not want to be named, said the dispute was over 12 months old, with the anti-dog behaviour "minor" in nature, with dog-poo bags provided by council taken from their dispenser.

"We have had faeces in the park, placed around the roads of the park and strategically placed on the gate, so when you open it you come in contact with it," the resident said.

In a statement today, Tasmania Police confirmed they were "aware of the incidents and have conducted investigations".

The tensions have been building for over a year, residents said. ( Facebook: Down and Dogless )

Poo turns out to be human, not canine

Following recent dog baiting incidents in the Hobart area, Lenah Valley residents were concerned for the safety of their dogs.

Testing of faecal matter organised by a local resident resulted in a negative result for poison, however results revealed the poo to be of human, not canine, origin.

"Through that testing, and eyewitness accounts, we could confirm that the matter being left behind was actually human faeces," the resident said.

Following the revelation, residents liaised with Hobart City Council and Tasmania Police to determine the best course of action, with leaflets dropped to letterboxes advising of the situation.

As residents have become more vigilant, the number of faecal discoveries has fallen to "every two or three days", the resident said.

"More and more people are aware of the behaviour and we are having more people keep an eye out," she said.

According to residents, the scatological deposits are moving away from the park to nearby Firth Road, with reports of private driveways being targeted within the last two days.

Some residents have also reported verbal abuse and harassment occurring at the park and in the area, with dog owners lodging a number of reports with Tasmania Police.

"We just want the behaviour stopped, because we think it is unsafe for our community," the resident said. "We take a lot of pride in our park."

Police said they had held discussions with residents and the local council over the matter and urged anyone with information to contact them on 131 444.
