Breed History:

The Jug is a designer crossbreed developed by crossing the Jack Russell Terrier with the Pug. The breed gained popularity in the United States and Australia during the late 20th and early 21st centuries as companion designer dogs became increasingly common.

Breeders aimed to combine the playful and energetic personality of the Jack Russell Terrier with the affectionate and adaptable temperament of the Pug. The result is a lively, compact, and entertaining companion dog that fits well into many family lifestyles.

Because the Jug is a mixed breed, appearance and personality may vary depending on which parent’s traits are more dominant.
