Yes, the teething process can affect a puppy's appetite and eating habits. As baby teeth fall out and adult teeth come in, puppies may experience gum soreness and discomfort, making eating less appealing. They might eat more slowly, be picky about food texture, or temporarily lose interest in eating. Softening their kibble with water or offering wet food can help ease discomfort. Monitoring their eating habits and ensuring they maintain a healthy diet is crucial during this period. Consult a veterinarian if significant changes in appetite or weight occur.
