9. Scottish terrier
There's a reason we see the Scottish terrier adorning sweaters and holiday gear — it's super-adorable! Their thick eyebrows and stout build make them resemble old men, in the most charming way.
With more than just cute looks, the Scottish terrier makes a wonderful watchdog. Witty and hypoallergenic, it's another small dog breed best suited for adults and older children.
