Transmission of transmissible venereal tumor of the dog to the coyote.

Three coyotes experimentally implanted with cells from a transmissible venereal tumor of a dog developed neoplasms. Histopathologic appearances of the tumors in the coyotes were similar to those described in the dog. Attempts to transmit the tumor to suckling mice, rats, hamsters, kittens, and opossums were not successful.
