Cojacks are designer dogs made by mixing the Jack Russell Terrier and the Pembroke Welsh Corgi. These dogs have pointy ears, short and stout legs, straight tails, and almond-shaped eyes. As they are a hybrid, they have a very limited history to speak about.
The Kojack, like its parents, is a very amicable and intelligent dog. Although they are used as companion animals, it has a herding desire which it inherits from Jack Russell. This will make the dog more energetic, but it can be controlled by diverting it to training and playing. They are loyal to their family and love being the center of attention. Prolonged periods of loneliness will grow destructive behavior in them. They do not bark excessively but can do so in case they spot a stranger. Also, they are experts in learning new tricks.
