8. Adult Labrador Retriever

And lastly, let's talk about the Labrador Retrievers. These happy, energetic dogs will give you all their love, but you must return it. For many seniors, that's just too much of an ask, which is why it's recommended to adopt an older Lab.

Get yourself a 4+ year-old Lab, but be prepared to have frequent walks and have enough space for your new friend to move comfortably. A calm adult Lab can provide years of loyal, gentle friendship, and that's all you can ask for.
