Who found the dog mosaic from Pompeii?

The dog mosaic from Pompeii was discovered by archaeologists during the excavation of the ancient Roman city, which was buried by the eruption of Mount Vesuvius in 79 AD. It was unearthed in the House of the Tragic Poet in the 19th century, specifically in the mid-1800s, as part of a broader effort to uncover and study the ruins. This mosaic features a depiction of a dog on a leash, and it has become one of the iconic artifacts representing daily life in Pompeii.
