We got a dog today at the big event that was going on but she is unfortunately very aggressive and attacked other animals as well as going after my children, I'm very much on edge with this dog at the house and am needing assistance.

I would try and see if you can help her to adjust. Our pup had been returned to the society and we knew that unless she did something like bite us or our kids, we were going to do everything in our power to not take her back. I heard a sad statistic that over half of the animals adopted at events will be returned the next week. Hopefully, things will work out for you. Just speak in a soothing voice and maybe that will help the pup.

I would contact them about it

She will take time to adjust and be sure to place your hand over her eyes while feeling calm. She is acting like the boss and you have to teach her. Shalom
