It's important to monitor your dog's eating habits to ensure they are receiving the right amount of food. Both overeating and underfeeding can have negative effects on your dog's health and well-being. Here are some signs to look out for:

Signs of Overeating:

• Weight Gain: If your dog is consuming more calories than they are burning, they may start to gain weight. You may notice a gradual increase in body fat, a rounder appearance, or difficulty feeling their ribs.
• Increased Food Consumption: If your dog is constantly begging for food or finishing their meals quickly and still acting hungry, it could be a sign that they are overeating.
• Digestive Issues: Overeating can lead to digestive problems such as diarrhea, vomiting, or excessive gas. If your dog is experiencing frequent gastrointestinal issues, it might be due to overconsumption.
• Lack of Energy: Dogs that are overeating may become lethargic and lack energy. They may be less interested in physical activities or playtime.

Signs of Underfeeding:

• Weight Loss: If your dog is not getting enough food, they may start to lose weight. You may notice their ribs or spine becoming more prominent, and a decrease in muscle mass.
• Incessant Hunger: Dogs that are not getting enough food may constantly act hungry, even after eating their meals. They may start scavenging for food or begging for scraps.
• Coat and Skin Problems: Underfed dogs may have a dull, dry coat, and their skin may become flaky or itchy. They may also experience hair loss or develop sores.
• Lack of Muscle Tone: If your dog is not receiving adequate nutrition, they may have a lack of muscle tone and appear weak. They may struggle with physical activities that were once easy for them.

It's important to note that the signs mentioned above can also be indicative of other health issues. If you suspect that your dog is overeating or underfeeding, it's best to consult with your veterinarian for a proper diagnosis and guidance on their diet.
