Is a 4.2 pound yorkie bad?

It is not necessarily bad for a Yorkshire Terrier to weigh 4.2 pounds, as the weight range for this breed can vary depending on several factors such as age, gender, and genetics. However, it is important to monitor your dog's weight and ensure they are not overweight or underweight. Overweight or underweight dogs may be at risk for certain health problems. You can consult with your veterinarian to determine the ideal weight range for your Yorkshire Terrier and discuss proper nutrition and exercise to maintain a healthy weight.
