I have a 2 year old wire haired jack russel who is 13 inches in height, what is the average weight of a jack russel of his height? (Stuart Smith - United Kingdom)
An average adult Jack Russel dog should be between 12 and 14 inches in height - so your dog is very average. For this height, the weight should be approximately 14 or 15 lbs.
