It is generally recommended that puppies be released from cages when they are over 2 months old. It is not recommended to keep puppies in cages for long periods of time, as this may lead to abnormal behavior and, in severe cases, depression. Puppies do not need excessive care at this stage and can be appropriately allowed to exercise, which can promote the development of the puppies' bones.

Owners can usually use Frisbees and other toys to play with their puppies, and they can take their puppies out after being vaccinated.

The resistance to infectious diseases will be reduced in the external environment, and the cage can reduce the chance of indirect contact with viruses;

2. Puppies do not have the habit of excreting in a fixed place. These puppies need to be trained and dispersed It may cause urination and defecation, which is not conducive to the dog's integration into family life;
