"Once he got on some medication and he was consistently fed and having space to move about - to be able to use his body - he slowly started putting weight on and getting better and also, he started showing a puppy factor," Rovetto recalls.
"He really truly was just a loving little dude," she adds. "There is nothing more perfect than a Cletus kind of dog because they're exactly what you don't expect."
And, of course, there's that flair for fashion.
At first, Rovetto, who fostered Cletus, started putting him in sweaters so people wouldn't fixate on his wobbly frame.
"It kind of didn't make people gawk at him," she says.
But no one could ignore the fact that Cletus certifiably slayed it in sweaters.
