Adopt a Mini Atlas Terrier, Dog Breed Guide


The Mini Atlas Terrier or also called Miniature Atlas is the “middle” size variety of the Atlas Terrier Breed. Like the Standard and Toy variants, the Mini Atlas Terrier is very much like the Jack Russel Terrier breed in regards to personality and temperament. The distinguishing marks that set the Mini Atlas and the two other size varieties of this breed is the coat color. Atlas Terriers come in solid or merle colored coats.

The Mini Atlas Terrier was bred to develop a superior line of Jack Russell Terrier, with reduced chances of deafness. Jack Russel dogs are known to have been developed primarily for hunting traits and not for the looks, today they are being bred for cosmetic reasons which resulted in most Jack Russell dogs having hearing problems. The Atlas Terrier was created and developed to stop this.


A Mini Atlas Terrier is a sociable, devilish, happy, faithful, and affectionate dog. It is energetic and docile, yet absolutely bold. A Mini Atlas Terrier will enjoy playing with your children as long as the playing stays “friendly” and the dog does not start to fear for its safety and/or see himself above the kids in the pecking order. They are extremely intelligent, and will enjoy trying to outsmart their owners at every turn; they will test the boundaries and push the limits, so owners need to be on their toes.

Bred For

They were developed to defeat Jack Russel’s gene that causes terriers to be prone to deafness.


The Mini Atlas Terrier will do okay in an apartment if it is sufficiently exercised. They are very active indoors and will do best with at least an average-sized yard. If the Atlas Terrier is kept in an apartment, the dog should have a person home with it during the day unless the dog is crate trained.


The Mini Atlas Terrier comes in two coat varieties, smooth and wire. Neither are high-maintenance coats. Special grooming is not required on your wire coated dogs


Early socialization should be done to avoid unruly behavior when joined by other dogs as the Mini Atlas Terrier can be very dominant.


All the size varieties of the Atlas Terrier breed went through an extremely controlled breeding program. All specimens used were tested to be healthy. The breeding program also required the foundation stock to be monitored into their senior years as longevity was a concern as well. To this day no major health problems have been detected.


Like the Jack Russell, the Mini Atlas Terrier will exercise and amuse itself in a yard, but without supervision, its choice of activity may not be to your liking. They thrive on being your shotgun buddy and anywhere you go, they would like to be with you. They need to be taken on long daily walks. They excel in active sports, like agility, fly-ball, and racing. We like to say that a tired Mini Atlas is a well-exercised owner.
