Association Between Protein Content in Dry Dog Food and Aggression in Golden Retriever Dogs

Area of Science:

• Veterinary Nutrition
• Canine Behavior Studies

Background:

• Dietary components significantly influence animal health and behavior.
• Understanding the impact of macronutrients like protein on canine behavior is crucial for well-being.

Purpose of the Study:

• To investigate the association between dietary protein levels in commercial dry dog food and specific behavioral outcomes in Golden Retrievers.
• To determine if protein content in dog food correlates with behaviors such as rivalry and separation anxiety.

Main Methods:

• Prospective cohort study involving Golden Retrievers fed commercial dry food.
• Dietary protein categorized into high (≥30%), medium (21-29%), and low (≤20%) levels.
• Behavioral data collected using a validated questionnaire, with analysis via logistic regression.

Main Results:

• Dogs fed high-protein diets showed a 1.3 times increased likelihood of dog rivalry compared to medium-protein diets.
• Dogs fed low-protein diets exhibited a 1.4 times increased likelihood of separation-related behavior.
• Adjustments were made for sex, reproductive status, and lifestyle factors.

Conclusions:

• Dietary protein content is associated with specific behavioral patterns in dogs.
• Clinicians should consider a dog's diet when assessing and treating behavioral issues like aggression and separation anxiety.
• Further research into specific nutrient-protein interactions and behavior is warranted.
