Determining a puppy’s age is crucial for providing appropriate care, training, and socialization. Several methods can help estimate a puppy’s age, including physical characteristics, teeth development, and behavior.
Physical characteristics that indicate a puppy’s age include size, weight, and coat condition. Newborn puppies are tiny and weigh only a few ounces. Their coats are often short and soft. As they grow, puppies gain weight and their coats become thicker and longer.
