Grain-free dog food does not contain grains like corn, wheat, rice, or barley, and instead uses alternative ingredients such as sweet potatoes, peas, and lentils as carbohydrate sources. Regular dog food, on the other hand, often includes grains as a primary source of carbohydrates. Grain-free food is typically recommended for dogs with grain sensitivities or allergies, while regular dog food can be suitable for most healthy dogs.

A picky eater may show signs like leaving food uneaten, turning away from their meals, or eating only certain foods. Dogs may become picky due to food sensitivities, boredom, or a lack of interest in the same food every day. If your dog consistently refuses to eat or shows signs of discomfort after eating, it might be a good idea to consult your veterinarian to rule out any health concerns.

When switching dog food, it’s important to transition gradually to avoid digestive upset. Start by mixing a small amount of the new food with their current food, gradually increasing the new food while decreasing the old food over a period of 7-10 days. This slow transition allows your dog’s digestive system to adjust to the new formula without causing discomfort.

The amount of food your dog needs depends on factors such as their age, breed, activity level, and weight. Most dog food packaging includes feeding guidelines based on your dog’s weight and age. However, if you're unsure, consult with your veterinarian to determine the proper portion sizes. Overfeeding can lead to obesity, while underfeeding can cause malnutrition.

Feeding your dog homemade food is possible, but it requires careful planning to ensure that your dog receives balanced nutrition. Homemade food may not contain all the essential vitamins, minerals, and nutrients that your dog needs. If you decide to cook for your dog, it's best to consult with a veterinarian or pet nutritionist to ensure their diet is complete and well-balanced.
