A small but sturdy dog, the Havanese is one of the most popular dogs for families. They generally weigh around 10 pounds and stand only 10 inches tall. Their coat requires a great deal of combing, especially if it is curly. Havanese dogs are great for seniors because they are incredibly loyal and sociable. They do not do well if left alone for hours during the day, making them perfect for a retired person. As well, they are one of the smartest toy dogs, and can be easily trained for a wide range of tasks.
