Macie is gone

I am so overwhelmed with emotions right now I can hardly TYPE straight. Tonight all 4 of us were outside. The dogs were in the back yard and we were outside of the back yard. Matt had repaired the fence where Sadie had dug a hole and gotten out but there was still a tiny little gap between it and the house so I had it all blocked up with a 5 gallon bucket full of water and a big metal dumptruck in front of it to be sure Macie couldn't get out--and she couldn't. Besides, I thought...we're RIGHT here...
Well, I was wrong.
She somehow scooted the dumptruck over and slid through the gate. We immediately saw her and so I started walking towards her calling her name all sweet-like. She took one look at me and took off like a speeding bullet. I ran as FAST at my feet could take me (thank God I had on tennis shoes!!) I ran about a mile down the road until I was about to collapse. Matt finally came up behind me in the truck and we followed her until she stopped and I jumped out and tried to call her to me...but again...one look at me and she darted off again. It has been an hour and 15 minutes that we have been chasing her like this...until she ran into a heavily wooded field where we couldn't go. We went around and around the fence with a flashlight calling her name. But nothing. I called my mom and dad and they set out looking too. We circled the area we last saw her over and over and over until now its so dark we can't see anything so we just came back home. I don't know what to do. I've prayed. I've PLEADED with God to PLEASE not let this happen again. Why do I keep losing my puppies? First Sadie..now Macie? I feel like I'm being punished. How can you pray something with your whole heart and believe completely that God is going to answer your prayer.....and it not happen? I feel like I gave EVERYTHING I had when I prayed that God would PLEASE let her come to me when I called her and I believed with my whole heart that she would. But when I saw her and I was only about 15 feet from her, I called to her and she took off....and that was the last time we saw her. Why?
Right now I'm so upset I don't even know a word to describe it. I'm FURIOUS and brokenhearted all at the same time. I feel horrendous guilt that I should have NEVER let her out in the backyard knowing that there was a gap in the fence...even if I did have it blocked.
THIS IS JUST NOT FAIR AND IT STINKS!!!!!
I know it will be a miracle if she makes it alive. There are cyotes everywhere out here. Plus, she's so little...she's nearly impossible to see on the road.
At this point the only thing I can hope for...is that somehow, someway she'll come back. I know it will be a miracle...but I do serve a miracle-working God.
