The phrase "rehome a dog/rehome a pet" means giving away a dog to a new home. In recent years, this phrase has gained popularity and replaced phrases like "giving up a pet," "surrendering a dog to a shelter," or "getting rid of" a dog. "Rehoming" communicates a more compassionate transfer of pet ownership. To rehome a dog specifically implies that the person is looking for a new home for their pet, rather than abandoning it or carelessly giving it away.
