The images classification is one of the most common applications of deep learning. Images of dogs and cats are mostly used as examples for image classification models, as they are relatively easy for the human eyes to recognize. However, classifying the breed of a dog or a cat has its own complexity. In this paper, a fine-tuned pre-trained model of a Keras’ application was built with a new dataset of dogs and cats to predict the breed of identified dogs or cats. Keras applications are deep learning models, which have been previously trained with general image datasets from ImageNet. In this paper, the ResNet-152 v2, Inception-ResNet v2, and Xception models, adopted from Keras application, are retrained to predict the breed among the 21 classes of dogs and cats. Our results indicate that the Xception model has produced the highest prediction accuracy. The training accuracy is 99.49%, the validation accuracy is 99.21%, and the testing accuracy is 91.24%. Besides, the training time is about 14 hours and the predicting time is about 18.41 seconds.
