SHUTESBURY — On his first day at Shutesbury Town Hall, a week before officially being sworn in as the Police Department’s first K-9 officer, Charlie provided a calming distraction for a stressed and flustered resident who had come to the town offices.

Offering such assistance, as well as visiting the elementary school, meeting senior citizens and participating in community events, are expected to be among the duties for the town’s newest officer, a 9-week-old mini Aussiedoodle doing joint patrols alongside Police Chief Kristin Burgess.

“His sole responsibility will be comfort,” Burgess said. “That’s his only job.”

At a brief ceremony Monday, Charlie, who weighs just 3 pounds and is the smallest of a litter born in Pennsylvania, joined the police force. After the oath was administered by Town Clerk Grace Bannasch, Charlie was given an embroidered badge that will be sewn onto his harness.

Before Burgess found the puppy and traveled to western Pennsylvania to pick him in late January, the chief discussed having a comfort dog with school administrators, senior citizens and others.

“I found an overwhelming response of positivity in that direction,” Burgess told the Selectboard, which approved Charlie’s appointment at its Jan. 30 meeting.

For the youngest students, Charlie, who will grow to be about 10 pounds, will be perfect. “Smaller children tend to do better with smaller dogs, because they are not so overwhelming,” Burgess said.

The Selectboard also adopted a comfort dog policy, similar to ones used by other agencies in Franklin County and modeled after Whately’s policy. Burgess previously spoke to Whately Police Chief James Sevigne Jr. about the program there.

In addition to Whately, Greenfield and Belchertown are among other nearby communities with comfort dogs, though Charlie is smaller than the poodles, Labrador retrievers or St. Bernards often used in the line of work.

The costs to the town are minimal. Burgess will own Charlie and pay for his veterinary bills, and for grooming, housing and feeding him. If he’s injured in the line of duty, the town would pay reasonable veterinary fees, though this is unlikely since he is not a task dog sniffing out bombs, drugs or firearms, or finding missing people.

Charlie will get training as a comfort dog and be certified by the American Kennel Club, Burgess said, adding that he’s already showing he’s cut out for the work.

“He’s a natural,” she said.

His work will also include providing sympathy to families displaced from their homes or those in need following domestic violence.

“Charlie’s calm and sweet demeanor takes people down a little bit,” Burgess said.

Having a comfort dog is important in a small town that doesn’t have access to money for emergency mental health co-responders who can join police in helping people in crisis or having a difficult time.

At the Selectboard meeting, Bannasch praised the idea of having this new mental health support, recalling when growing up in town that children were accustomed to seeing Ziggy, who fulfilled the role of comfort dog at the M.N. Spear Memorial Library during Judith Seelig’s tenure as library director between 1999 and 2004.

Burgess thanked the Selectboard for endorsing a vision to continue pursuing a community policing model.

“This is taking the department to the next level of community policing,” she said.
