This is the moment a chihuahua reacts to meeting its owner’s newborn baby for the first time.

The footage, captured at a home in Dublin on March 14, shows chihuahua Quica excitedly wagging her tail as she sees 4-day-old Nicholas lying in his father’s arms.

Nicholas' father then approaches Quica to show her the new member of the family more closely.

Quica's reaction leaves him stunned when the dog lies on her back as if it was mimicking the baby.

Nicholas' mother writes: ''When I was pregnant my chihuahua Quica was very protective of my bump.

''Whenever my husband would attempt to rub my belly or touch my bump Quica would instinctively react and snap at my husband to stay back.

''Consequently, we knew that Quica would be eager to meet the precious goods.

''We were stunned by Quica's reaction which was to immediately submit to Nicholas.

''Quica displayed a remarkable motherly instinct.

''Ever since Quica stands guard by Nicholas' crib and watches over his every move while eagerly wagging her tail.''

When I was pregnant my chihuahua Quica was very protective of my bump. Whenever my husband would attempt to rub my belly or touch my bump Quica would instinctively react and snap at my husband to stay back! Consequently, we knew that Quica would be eager to meet the precious goods she was guarding so we decided to film the moment they first met. We brought Nicholas home from hospital at 4 days old on 15 March. We were stunned by Quica's reaction which was to immediately submit to Nicholas. She displayed a remarkable motherly instinct. Ever since Quica stands guard by Nicholas' crib and watches over his every move while eagerly wagging her tail.
