* Individual Variation: Just like humans, dogs have different body types and milk production capabilities. Some dogs may naturally have more milk than others.
* Breed Differences: Some breeds may have been selectively bred to produce more milk than others, but this isn't a hard and fast rule.
* Factors Affecting Production: Milk production is influenced by factors such as the dog's age, health, diet, and the number of puppies she's nursing.
Important Note: It's crucial to remember that milk production is a natural and healthy process for lactating dogs. If you have concerns about your dog's milk production, it's best to consult a veterinarian.
