The objective of this study was to quantify physical activity and dietary energy intake in 35 dogs enrolled in a controlled weight-loss program and assess relationships between energy intake and physical activity, sex, age, body weight and body condition score. Dogs were fed a therapeutic diet with energy intake restrictions to maintain weight loss of approximately 2% a week. Collar-mounted pedometers were used to record the number of steps taken daily as a measure of activity.
Mean Â± SD daily energy intake per unit of metabolic body weight (kg 0.75) of active dogs was significantly greater than that of inactive dogs (53.6 Â± 15.2 kcal/kg 0.75 vs. 42.2 Â± 9.7 kcal/kg 0.75, respectively) while maintaining weight-loss goals. In regression analysis, only the number of steps per day was significantly associated with energy intake.
Increased physical activity was associated with higher energy intake while maintaining weight-loss goals. Each 1,000-step interval was associated with a 1 kcal/kg 0.75 increase in energy intake.

New shelter data casts doubt on whether the pet population and pet ownership are truly growing.
While the pandemic caused unprecedented suffering worldwide in 2020, the disruptions to dogs, cats and other pets adoption numbers may normalize in 2021.
