The 1909 First Presidency says animals were not created in God's image, but will be "perfected and perpetuated in the Hereafter."
First Presidency (Joseph F. Smith, John P. Winder and Anthon H. Lund), "The Origin of Man," Improvement Era 13, no. 1 (November 1909):
He made the tadpole and the ape, the lion and the elephant, but He did not make them in His own image, nor endow them with godlike reason and intelligence. Nevertheless, the whole animal creation will be perfected and perpetuated in the Hereafter, each class in its “distinct order or sphere,” and will enjoy “eternal felicity.” That fact has been made plain in this dispensation.
