The Jack Russell Terrier is a source of unlimited energy that loves its owners. They are extremely loyal to their family and love their owners infinitely. Although initially these dogs were created and bred as hunting dogs, today they everywhere live in families as pets who have never hunted for anything other than a toy or their own tail in their lives.
A large amount of energy is not a problem – the dog is very active, loves to walk and play outdoor games outside and at home. However, they are not very destructive, and with proper education and care, they will be the smartest and most beautiful dog in the world. Of course, if you do not need security functions, when the dog must stop the attacker and at the same time be able to inflict significant damage on him, simply due to its size and strength.
