What Happens When a Dog Eats Too Much?

When your dog eats too much, it can lead to bloat, obesity, and, in puppies, skeletal issues. While it’s tempting to give in to those puppy dog eyes and feed your pet as much as they want, it’s not what responsible pet parents do. Instead, feed your pet according to proper guidelines, so they maintain a healthy weight and stay on the path towards a long, happy life.

Obesity in pets

While all overfeeding won’t result in such an extreme case of obesity, even being slightly overweight can diminish your pet’s health. Overweight dogs are more prone to develop:

• Heart problems

• Diabetes

• Hypothyroidism

• Joint issues

• And more

Bloat from overfeeding

Overfeeding can contribute to a dangerous condition called bloat or gastric dilatation-volvulus (GDV), especially in dogs prone to the condition. Food bloat occurs when the dog’s stomach gets too full of food or gas, causing it to expand and making it more likely to twist. While the exact cause of bloat isn’t fully understood, overeating or eating too quickly are recognized risk factors. Large, deep-chested breeds and mixes such as Great Danes, German Shepherds, Boxers, and Standard Poodles are at higher risk, as are older dogs.

This condition is potentially life-threatening, so see your vet immediately if you notice the following symptoms:

• A swollen stomach

• Pacing

• Restlessness

• Trying to vomit but not producing anything

• Rapid heartbeat

• Shortness of breath

How much should I feed my dog?

Many pet parents who overfeed their pets aren’t aware of how much food is a proper amount. While most dog food packages have guidelines printed on them, how much you should feed your dog depends on factors like their size, age, breed, activity level, and health. For example, active dogs that get regular exercise or physical work (e.g., herding) may need more food to fuel their energy, while older or less active dogs require fewer calories to avoid weight gain. The best way to be sure you’re feeding your dog a proper diet is to talk to your vet.
