Here are 5 Reasons Why:

  1. With their average lifespan set at a whopping two decades at most, Jack Russells make for exceptional long-term companions, especially for active owners who can keep up with their exuberantly playful and high-spirited nature.

  4. Jack Russell’s are also ideal four-legged friends for first-time owners. Not only are they genuinely gentle, loyal, loving, and affectionate towards their handlers, Jack Russell Terriers are highly alert and extremely protective long-term guard dogs.  
  5. There’s nowhere you can’t take your jovial Jack. When compared to other dog breeds, Jack Russell’s are extremely adaptable to lifestyle changes and various living environments.


Making for a lasting addition to your life and the loved ones you share it with, the tough and tenacious Jack Russell Terrier is a cut above the rest, and owning one can bring extended elation and enjoyment into your life for longer than most dog breeds.
