Dream I caused my dogs death

Very disturbing dream that I’m convinced is symbolic of some sorts and wondering y’all’s insight:

Dream I accidentally caused my dogs death

Warning this is disturbing:

I had a realistic dream where after a series of events I’m walking my dog with my mom in a building and we come across another stray German shepherd (every dog I’ve had has been a German shepherd including the one my moms walking) I’m afraid of them fighting so I grab the leash on the other German shepherd and try to search for its owner. I search through the building a long time, what feels like days. The dog and I build a bond over that time and she’s becomes very trusting and obedient. She can follow me around without the leash now. Because of this I’m reluctant but still think it’s the right thing to do to find her owner. We walk up a really long flight of stairs to an attic, and I’m sure the old owner in this room. But instead I see two adults I vaguely recognize and a girl from a past relationship. I see her face is very swollen and bruised as if someone had beaten her. I am startled and climb back down the abnormally high flight of stairs. When I get to the bottom I realized these are attic door stairs (kind of like a ladder) so it’s a lot harder for my dog to come back down then up. I try to get the dog to walk down thinking I can catch her momentum, but she’s terrified of the height (I’m not completely sure of the dogs gender but she reminds me of my female German shepherd Stella). I stand on a large group of cardboard boxes to the right hoping to catch her if she jumps. Im kinda in a rush and try to convince her to jump, to trust me despite her being terrified. Finally she gives in and trusts me and tries to jump, but she almost falls in the opposite direction. She smacks the concrete and it’s awful. She’s all mangled, bones broken, even her skins torn off, there’s so much blood and organs loose. It looks as if she’s already dead. I desperately try to save her I try to keep her in tact using my shirt, I get some help from college students but they seem to be kind of apathetic considering how horrifying the situation is. I know there’s a campus hospital nearby so I carry my dog in my arms just covered in blood. I keep trying to find the emergency room of the hospital, but everyone I try to get help from seems so disinterested and occupied. The nurses give short and vague instructions that lead to nowhere. No one really cares , everyone is just doing the bare minimum of what’s required with their job. I continue desperately running all over the hospital knowing that I’m likely carrying around what is now a corpse in my arms. I feel a tremendous amount of guilt for getting the dog to trust me and indirectly causing her death. I’m not relieved the dream is over bc there is nothing I can do to protect her now.

Any interpretation might be helpful and make feel less depressed.
