Where can I find my parakeet?

Well, I was going to an old church without my sister, where my sister took the bird outside and put it on a tree (she is 15, older than me), the dog went to the tree and tried to get up there, i think my sister thought he dog had the bird in its mouth, but she said it was a leaf. After that she could not find it. The bird is still young, so can it survive, if it can, where can i find it. I have few fruit trees, such as donut peaches, i think thats all. I have some flowers too. I only had that bird for 2 days but i feel close to it. I really wanted to find it. My family tried to replace it with a new bird, which i found in my cage, but i really liked my first one. I have 5 dogs, only 1 aggressive, what are the chances of my bird still alive? Where is the best possiblity to find it? I am going to check tomorrow because its too dark, so where can it be in the morning? I can check for a little at night too, so please help! Every time i said bird i mean parakeet. There is one tree i put it on frequently. Its wings are also clipped
