  1. All data are expressed as median (range). M: male; NM: neutered male; F: female; NF: neutered female; CKCS: Cavalier King Charles Spaniel
  2. aRate of weight loss expressed as percentage of starting body weight lost per week
  3. bRefers to the percentage change in starting mass calculated as follows: ([start mass – end mass] ÷ start mass) ×100%
  4. cEI: energy intake expressed as metabolisable energy (in kJ [Kcal]) per kg of metabolic body weight (BW0.75) per day
