I need to get this off my chest.

I'm really frustrated right now. A few months ago, I started feeding our neighbor’s dog, and it’s been a no-brainer for me because I love dogs and can't stand to see any of them go hungry. I’ve accepted that I rarely see her owner because of work, but I just found out that they moved out last week at dawn without taking the dog with them. I’m infuriated! The dog has always been outside, and she plays with a particular stray in the neighborhood, so she doesn’t roam far. I thought the owner was still around until I checked with my sister. Now, I don’t know what to do. I already have two dogs, and my mother and her husband aren’t keen on taking in more pets, especially with my upcoming departure. I’m seriously considering posting about her for adoption because it breaks my heart to see her abandoned. She’s a great dog, and I’m confident someone would love her. However, I’m torn because I’m not her owner, yet her owner clearly left her behind without a second thought. For now, I’ve let her stay on our back porch, but my stepdad insists that we can't make this a permanent arrangement since everyone is busy, and I won’t be here much longer. I need to figure this out. 😭
