Barking, biting, and aggressiveness are the three common characteristics of the 3-month-old goldendoodle behavior. You must be careful about these things and understand the puppy’s behavior.


People and noises that are new to your puppy may make her bark. This is called her “socialization period,” which lasts from about 6 to 12 weeks of age and lasts until your puppy is ready to be a dog.

When your puppy is about four to six months old, it may start to do this again.


Your Goldendoodle will start teething around this time. When their gums hurt, they will want to bite and chew on everything they can.

During the 3 months, the Goldendoodle loses its baby teeth and grows new permanent teeth, which means they are likely to chew and play-bite.

Those puppy teeth can hurt. It’s not for the faint of heart, and those puppy teeth can be painful.
