1. Obesity: Overfeeding is the leading cause of obesity in dogs. Obese dogs are prone to various health problems, including heart disease, joint problems, diabetes, and certain types of cancer.
2. Diabetes: Overfeeding can also lead to diabetes, a condition in which the body cannot effectively use insulin to control blood sugar levels. Diabetes can cause several severe health problems, including blindness, kidney failure, and nerve damage.
3. Joint problems: Overweight and obese dogs are more likely to develop joint problems, such as arthritis and hip dysplasia. This is because excess weight puts extra strain on the joints.
4. Heart disease: Overfeeding can also lead to heart disease. Obesity can increase the risk of developing heart conditions such as high blood pressure and congestive heart failure.
5. Increased risk of certain types of cancer: Overfeeding has also been linked to an increased risk of certain types of cancer in dogs, such as mammary gland cancer and lymphoma.
6. Skin problems: Overfeeding can lead to skin problems, such as dermatitis and hot spots. This is because excess weight can cause the skin to become stretched and irritated.
7. Dental problems: Overfeeding can also lead to dental problems, such as tooth decay and gum disease. This is because excess weight can cause the teeth to become misaligned and the gums to recede.
8. Behavioral problems: Overfeeding can also lead to behavioral problems, such as aggression and anxiety. This is because obesity can cause dogs to feel uncomfortable and irritable.
