No Dogs Allowed is a song written by the Sherman Brothers for the film, Snoopy, Come Home. It was sung more than once for Snoopy going to places that don't allow dogs and was sung by the original voice for Tony the Tiger and fellow Melloman, Thurl Ravenscroft.
No dogs allowed, you're not our crowd. Obey the signs and boundary lines. You're out of place. You bark and chase. You're not our crowd. No dogs allowed.
