A beagle and Chihuahua mix is called a "cheagle." Due to the similarities between Chihuahuas and beagles, their temperaments are also closely matched with each individual dog breed.
Like Chihuahuas and beagles, cheagles are playful and affectionate dogs that can be aggressive if they feel they are threatened. They are great dogs for families with other dogs or children. Cheagles generally have the small size and coloring of a Chihuahua with the head and droopy ears of a beagle, though this may vary. Cheagles are an average of 12 pounds, with a proper diet and exercise routine, and have an average life expectancy of 15 years. There are no known health issues specific to this mixed breed.
