Jack Russell Terrier Ideal Weight Range
5–8 kg
Jack Russell Terriers are predisposed to primary lens luxation, a hereditary condition where the lens detaches and can trigger acute glaucoma, as well as a hereditary vasculopathy affecting the skin and extremities. They are also among the terrier breeds most frequently affected by epilepsy. Dogs managing seizures are often on lifelong anticonvulsant medication. FitFido tracks both medication and weight in one place, making it easier to notice if either changes.
Your dog is more than a breed average.
A generic range is just a starting point. FitFido uses your dog's unique breed characteristics, age, body type, and activity level to calculate their target weight and construct a custom plan that adjusts as you progress.
Please note that a dog's ideal weight depends on many individual factors, including height, bone structure, and overall body condition.
