Jack Russell Terriers have a long history that runs 200 years back. John Jack Russell had bred this amazing dog breed in the early 1800’s in England. His primary ambition for developing this breed was to create a hunting dog.

Moreover, he wanted to create an independent dog with extreme energy, loyalty, and intelligence. As a result of that, this small-sized but energetic Jack Russell Terrier breed was designed. They are also known as the Parson Russell Terriers.

As a proud owner of two Jack Russells named Shaggy and Lenny, I would like to say that this dog breed is an excellent choice for new pet parents and apartment dwellers. They are so adorable and affectionate. Contrary to their body size, they have endless energy and intensity that will make your day bright and awake.

Origin of Jack Russell Terriers (History)

Origin of Jack Russell Terriers (History)

Parson John Russell developed this wonderful breed in the early 1800s in southern England. He wanted to create a working dog with high energy that can support his hunting purposes. Jack Russell Terriers could hunt small foxes, hounds, and rabbits because of their speed, small size, and high sense of smell.

They were popular among the hunting sportsmen who hunted as a sport or hunted on horseback. Eventually, Jack Russell became a necessary companion for hunters.

Jacks became family dogs later on with the recognition of the famous kennel clubs, namely the American Kennel Club (AKC), Dog Registry of America, Jack Russell Terrier Association of America (JRTCA), etc.

However, history shows that Jack’s first appearance in the USA had happened in the early 1900s. American Kennel Club identifies this bread as ‘Parson Russell Terrier”. According to the AKC popularity rankings, they are at 82 out of 197 breeds.

Highlights

Their adaptability to weather conditions is excellent. Jack Russell Terriers can tolerate hot or cold weather well.

  • There is a myth that they are not suitable for first-time dog owners. I completely challenge that idea as a proud owner of two Jack Russell Terriers. I didn’t face any issues, though they are my first dogs for this six years.
  • Jack Russell Terrier enjoys digging like all terriers. They are experts at making holes in a short time in every corner of the garden. That digging habit comes in their genes because they used to be hunting dogs a long time ago. However, my advice is, train them to dig in a particular place. That would be easier than prohibiting that habit.
  • They need regular exercises to release their energy. You can give them a walk of 30-40 minutes daily. Also, it is good for your health. Your Jack will be a perfect jogging companion for you.

But, if it is a guy that doesn’t care about dogs, Jack’s reaction could be aggressive. 

Typically, they are friendly with other dogs or pets. However, their fearless nature gives them a bossy attitude. That could be an issue when Jacks are with a bigger dog because bigger dogs will not tolerate this little man’s threats.
