Parson Russell Terrier: healthy weight & calories
A healthy adult Parson Russell Terrier usually weighs 5 to 8 kg (11 to 17.6 lb). That is a wide range because frame size varies a lot even within one breed, so how they feel under your hands matters more than the number alone.
Estimated for a Parson Russell Terrier at 6.5 kg, a healthy weight in the middle of the breed range. Resting energy is 70 × weight0.75 kcal; the multiplier below scales it up for how much they move and whether they are desexed.

| Mostly restsa few short potty walks | 342 kcal | 399 kcal |
| Short daily walks20 to 30 minutes total | 399 kcal | 456 kcal |

Puppies get roughly twice their resting energy while growing, about 570 kcal a day at this weight, but puppy needs change every few weeks so this is a starting point, not a fixed number. Seniors typically need about 10% less than an adult at the same activity level.
High energy dogs often gain weight when the exercise drops rather than when the food goes up. Keep the weekly plan steady and the portions weighed.
Studies of dogs a similar size to a Parson Russell Terrier found overweight dogs had a shorter median life span than lean ones, by 1.0 to 2.3 years (Salt et al. 2019). That is an association from observational data, not a promise, but it is one of the largest studies of its kind.
