**Key Considerations when Choosing:**

* **Your audience:** Who are you trying to reach? Are they beginners or more experienced dog owners?
* **The content of your site:** What kind of content do you typically publish?
* **SEO (Search Engine Optimization):** Consider relevant keywords like “狗狗飲食” (dog diet), “疾病預防” (disease prevention), “疫苗” (vaccinations), and “健康” (health) if SEO is important to you. Option 3 is the most keyword-rich.
* **Your preference:** Choose the description that best reflects your tone and the information you want to convey. I believe option 3 or 4 would be ideal.
