How much should a jack rat terrier mix weight?

Jack rat terriers, a mix between the Jack Russell Terrier and the Rat Terrier, generally weigh between 10 to 25 pounds (4.5 to 11.4 kilograms) on average, depending on their build and gender. Male Jack rat terriers tend to be slightly larger than females. It is important to keep in mind that weights can vary among individual dogs, and regular check-ins with a veterinarian can help monitor your pet's weight and overall health.
