Dogs may act weird around babies because they are unsure of how to react. They see babies as a new addition to their pack and may be overly friendly or scared. Dogs may also be protective of their owners and see the baby as a threat or become jealous of the attention the baby is getting. It's important to train dogs how to behave around babies and introduce them slowly. Dogs may act differently around babies, becoming more protective and hesitant around new people. Therefore, caution should always be exercised and never leave a baby alone with a dog. Dogs do change when you have a baby as they become more protective and territorial. Patience and continued socialization are key.
