Here's why:
* Puppies' nutritional needs change: As puppies mature, they begin eating solid food and need less milk. Their bodies start producing less of the enzyme lactase, which breaks down lactose in milk, making milk less digestible.
* Mother's milk production decreases: The hormonal signals that stimulate milk production decline as the puppies get older.
* Weaning process: The mother dog naturally starts to wean her puppies by decreasing nursing sessions and eventually pushing them away. This is a natural process and part of the mother's instinct to prepare her puppies for independence.
Factors that can influence the weaning process:
* Litter size: Larger litters may wean earlier as they compete for milk.
* Individual dog's temperament: Some mothers may be more patient with their pups than others.
* Health and nutrition of the mother dog: Stress, illness, or poor nutrition can affect milk production.
* Human intervention: Owners may choose to supplement with puppy formula or introduce solid food earlier to aid in the weaning process.
Important note: It's crucial to monitor the puppies' weight and development during this time. If you notice any signs of malnutrition, it's essential to consult a veterinarian.
In summary, female dogs don't abruptly stop feeding their puppies. The weaning process is gradual and involves a combination of factors.
