The newlyweds' Alaskan Klee Kai, Waldo, was killed last week (ends July 26), when he ran away from a dog walker and into a New York street, where he was hit by a car.
Now, Joe and Sophie have honoured their late pet with skin art portraits of the pooch.
Jonas Brothers star Joe revealed his tattoo on social media on Monday, July 29, and added the message: "R.I.P. my little angel," while actress Sophie posted, "I miss you, Waldo. Rest In Peace my little baby", alongside the art.
The couple filed a police report following their dog's death, but law enforcement sources tell TMZ the driver of the vehicle that killed Waldo is unlikely to be charged with any crime.
