Evaluation of weight loss protocols for dogs

Area of Science:

• Veterinary Medicine
• Animal Nutrition
• Canine Health

Background:

• Obesity is a common health concern in dogs.
• Effective and safe weight loss strategies are crucial for canine health management.
• Understanding the impact of different calorie restriction levels is essential.

Purpose of the Study:

• To evaluate the safety and efficacy of various canine weight loss protocols.
• To determine the impact of different percentages of maintenance energy requirements (MERs) on weight loss.
• To identify potential adverse effects associated with calorie restriction in dogs.

Main Methods:

• Dogs were assigned to receive 100%, 75%, 60%, or 50% of their estimated maintenance energy requirements (MERs) based on target body weights.
• Monitored for adverse health effects throughout the study.
• Assessed triiodothyronine (T3) levels and apparent MERs.
• Correlated the rate of weight loss with the degree of calorie restriction.

Main Results:

• No adverse health effects were observed across all tested weight loss protocols.
• Triiodothyronine (T3) levels and apparent MERs decreased in dogs fed 50% or 60% of MERs.
• Weight loss rate showed a linear correlation with calorie restriction, with individual variations noted.
• No significant difference in the final percentage of overweight was found between dogs fed 50%, 60%, or 75% of MERs.

Conclusions:

• All tested weight loss protocols are potentially safe for managing overweight dogs.
• Individual responses to calorie restriction can vary significantly.
• Severe calorie restriction may increase the risk of weight rebound in dogs.
