**Which one to choose depends on your overall WordPress site aims. Consider:**

* **Target Audience:** Are you tailoring to experienced dog owner or a general new to the topic?
* **Content Focus:** Does your site deeply explore detailed information about dog’s age, or does it just touch on general tips.
* **SEO:** If using SEO (Search Engine Optimization), keywords like “健康” (health), “照護” (care), “幼犬” (puppy), and “老年犬” (senior dog) in your tag description can help the description.

I hope this helps you! Let me know if you’d like me to adjust any of these based on the specific needs of your WordPress site.
