My sisters dog

Angel • 19 first time mom 💙 mommy to a 1 year old

My sister moved back in with us because her an boyfriend broke up an she brought her dog with her now I don't have a problem with her dog but my sister is never here really because she works all the time but her dog sleeps at my feet an if anyone comes home or they walk through the door he will bark an growl also I'm 38 weeks pregnant is it because he is protecting the baby or is just because he is becoming protective in general he is a red nose an he is almost a year old also please no rude comments because I don't know where to post this
