Firefighters were called out to rescue a Jack Russell that tried to squeeze through a metal gate.
The terrier had tried unsuccessfully to get through the gate on Duffryn Terrace, Wattsville at 5.30pm on Tuesday April 12.
A Risca fire crew attended the scene, and used hydraulic spreaders to bend the metal bars apart and free the dog.
A spokeswoman for the South Wales Fire and Rescue service said the dog was fine.
