Box-and-whisker dot plots comparing percentage weight loss in intact and neutered dogs over the 3-month study.
The boxes depict median (horizontal line) and inter-quartile range (top and bottom of box), the vertical lines depict 1.5 times the inter-quartile range, and individual dogs are shown by the black circles.

Fig 4.
Activity scores for dogs during the study.
Activity score was subjectively determined at each visit after a discussion between the veterinarian and owner (Table 3). At each visit, blocks with different colours represent the proportion of dogs assigned an activity score of -1 (red), 0 (blue) and 1 (green), respectively. The number of dogs assigned to each category is also shown.
Fig 5.
Quality of life (QOL) scores for dogs during the study.
QOL was subjectively determined at each visit after a discussion between the veterinarian and owner (Table 3). At each visit, blocks with different colours represent the proportion of dogs assigned a QOL score of -1 (red), 0 (blue) and 1 (green), respectively. The number of dogs assigned to each category is also shown.
Fig 6.
Food-seeking behaviour scores for dogs during the study.
Food seeking behaviour was subjectively determined at each visit after a discussion between the veterinarian and owner (Table 3). At each visit, blocks with different colours represent the proportion of dogs assigned a food-seeking behaviour score of -3 (red), -2 (orange), -1 (blue) and 0 (green), respectively. The number of dogs assigned to each category is also shown.
