Prepare for unexpected vet bills
What do you get when you cross two hyper but lovable dogs like the Patterdale Terrier and the Jack Russell Terrier? You get the Patterjack, the Energizer bunny of the canine world. Patterjacks are so friendly they love everyone, and their energy just keeps going and going and going.Â
These pups don't always look the same but they are usually no more than 14 inches high and weigh less than 16 pounds. Since their background is an ancestry of working dogs, they love to be helpful - but their version of helpful may be different than yours if you don't keep them actively stimulated!
Patterjacks can be stubborn and will require structured discipline and consistent rules. They are good family pets if they have been socialized and trained well.
