The Pembrooke Welsh Corgi is a popular pet, slightly smaller than the Cardigan. They make good family dogs but will not tolerate inconsiderate treatment - make sure any children understand the play and treatment rules. If they nip at your heels they're only trying to herd you into a group. Corgis make good apartment dogs if walked on a regular basis. They can be wary of strangers, and may be more excitable than Cardigans.
