cute dogs, cats, and other animals

Hi guys, new in this community with a question to do. We have two dogs at home, one of them senior. She seems to be more prone to notification sounds; my wife and I can't find an appropriate notification sound for our phones...our doggy seems to be pleasant with one we choose, but all of sudden it peaks an anxious behavior of wanting to go outside, like scare or something like that. Any advice? Don't know if it's hurting her or it's something else
