puppy, dog
狗 centers on a young or small dog: a puppy, or a dog in a general sense. The two meanings are closely related, with 'puppy' being the more specific application.
狗 combines the animal radical 犭 (dog) with 句, which likely contributes the sound. The character originally referred to a young dog or puppy.
The left side 犭 is a dog, and the right side 句 looks like a small curled-up puppy. Picture a tiny puppy curled into a ball: 狗 is a puppy.
For ク, imagine a cute puppy making a small 'coo' sound: coo -> ク, and the puppy is so adorable.
