Brittany: healthy weight & calories
A healthy adult Brittany usually weighs 14 to 18 kg (30.9 to 39.7 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 Brittany at 16 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.
| Activity | Desexed | Entire |
|---|---|---|
| Mostly restsa few short potty walks | 672 kcal | 784 kcal |
| Short daily walks20 to 30 minutes total | 784 kcal | 896 kcal |
| Active most days45 to 60 minutes, some play | 896 kcal | 1,008 kcal |
| Very activeruns, hikes or dog sport | 1,008 kcal | 1,120 kcal |
Puppies get roughly twice their resting energy while growing, about 1,120 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 Brittany 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.
