The video comes after Hendrix posted a picture of Harper Rose looking less than pleased at her their family dog, Maddie.
"MY TRIBE oh damn when I see these cuties hanging out it melts my heart," the new mum captioned the image.
"Our dogs have always been an important member of our family and we are so relieved that Maddie is so gentle and can be around our baby," she added.
Hendrix met her husband Alex Garner on the reality TV series Married At First Sight in 2015. Sadly, they experienced a miscarriage last year, but they say are "overjoyed" with Harper Rose.
Hendrix had an induced labour on November 14 after suffering pelvic problems and Harper-Rose was born safely weighing 3.37kg.
