My favorite animal is a dog. honestly, i love all animals. i like cats and hamsters, and fish and birds, and even domestic rats, but the dog is my favorite animal. as the saying goes, a dog is man's best friend. and i agree with that completely. dogs bring happiness and joy to a man. they are always very funny, always want to frolic and play in something, be it a ball or a simple bone. they protect the human's house from outsiders, guard their territory. i think dogs are very loyal man, his master. we can recall the legendary story of hachiko a dog, who was left waiting for a long time already dead master. hachiko is ideal loyal, faithful dog. moreover, the dogs are very intelligent and easy to tame. looking even vagrant dog's eyes, a feeling that he understands everything, sees everything. as if through the eyes of a dog to shine through her own soul. and who has never had a feeling of guilt when you see wandering hungry dog, pitiful looking straight at you? i think that everyone understands that the dog is one of the best animals. they are smart, bring joy into our lives. they guard our house, guarded by his master, and create a cosiness in the house. but the most important thing is that the dog is a faithful and loyal brothers our smaller.
