The American Kennel Club (AKC) states that Jack Russells should be between 10-15 inches in height at the shoulder and weigh between 14-18 pounds. However, these measurements are not set in stone and can vary depending on the individual dog’s gender, color & type.

In comparison to other breeds, Jack Russells are smaller than many medium and large breeds such as Labrador Retrievers, German Shepherds & Golden Retrievers. However, they are similar in size to other small breeds such as Chihuahuas and Pugs.

Jack Russell Weight – How Much Should Jack Russells Weight?

Female Jack Russells tend to weigh slightly less than male Jack Russells and there can be differences in weight between different coat types, such as rough or smooth.

To determine if your Jack Russell is at a healthy weight, you should be able to feel their ribs without seeing them. They should have a waistline that is visible when viewed from above and their belly should be tucked up. If you are unsure if your Jack Russell is at a healthy weight, consult with your veterinarian.
