The origins of Guard Dog

Courtesy of Abrams Comic Arts

Guard Dog (now known as “Sparky”) was first introduced in theMUTTScomic strip in 1995. Since his debut, the pup has become one of the most beloved characters in the strip.

Nearly three decades later, McDonnell says now was the right time to release a comprehensive book that encompasses Guard Dog’s past and present. “I’ve been promising it for way too many years,” he says.

Sparky was originally intended to be a “villain character” when they first came into the strip about a year after Earl and Mooch were introduced.

“I started drawing in my sketchbook what I thought was the typical nasty dog with big teeth protruding and I put a spike collar on them to look tough,” McDonnell says. “Then I put a chain on that spike collar to make them look tougher.”

But after doing so, the creator realized, “Oh, this isn’t a villain. This is a tragic character, thinking about all the poor dogs who are chained in their backyards … So that’s how Guard Dog started.”

02of 08The thought process behind freeing Guard DogThe Guard Dog Story.Courtesy of Abrams Comic ArtsReaders of the popular comic strip often questioned whether Guard Dog/Sparky would ever be saved and have his chain removed.“I’ve followed Sparky’s story for years, waiting for the day he would be freed and find his forever home,” Marisol said, in a statement shared with PEOPLE. Though it took many years for fans to get what they wished for, the decision to do so was always in McDonnell’s mind.“I always knew someday I’d free him,” the creator tells PEOPLE. “I’m friendly with a lot of animal organizations and groups and they all encouraged me to keep him on the chain because they thought he had a mission to raise awareness about the sad plight of tethered dogs.“The decision to finally free the character was “in part due” to his interaction with the Dalai Lama. “I got to visit him in India,” McDonnell explains. “I was just in a different place in a different mood and I thought it was time to free Guard Dog.”

Readers of the popular comic strip often questioned whether Guard Dog/Sparky would ever be saved and have his chain removed.

“I’ve followed Sparky’s story for years, waiting for the day he would be freed and find his forever home,” Marisol said, in a statement shared with PEOPLE. Though it took many years for fans to get what they wished for, the decision to do so was always in McDonnell’s mind.

“I always knew someday I’d free him,” the creator tells PEOPLE. “I’m friendly with a lot of animal organizations and groups and they all encouraged me to keep him on the chain because they thought he had a mission to raise awareness about the sad plight of tethered dogs.”

The decision to finally free the character was “in part due” to his interaction with the Dalai Lama. “I got to visit him in India,” McDonnell explains. “I was just in a different place in a different mood and I thought it was time to free Guard Dog.”

He was a chain dog that lived in West Virginia and was horribly abused,” Thomas explains. “He was our first child really.““Those are little characters that are a part of our life,” Thomas continues. “I think anybody who’s ever really let an animal be a part of their life and really be a part of their family just completely connects with Patrick’s message.”
