Am I trying too hard?

A woman on facebook shared a picture of a rescue dog who slipped her collar in Brooklyn Park on July 5, 2012.    I asked for some pictures and began getting things right away from this dog.   
I contacted the woman and told her where I thought she should look.  I was on the phone with her and I was able to tell her where things were and where I believed the dog, Rosie, was or had been.  I was on the phone with her for about an hour and a half. 
The next time I spoke with the woman I was on the phone for 3 1/2hrs!   I was telling her things that her search party and her hadn't even spotted yet.   I could see their headlights and their flashlights but they just couldn't find her.  
They have had people out there today, July 9th, 2012, in the same area and still no sign of Rosie. 
Has Rosie passed on and she was showing places she had been before she passed?   Is she really alive but now moved to a different part of the city?   
How could I know what some of these things were if Rosie wasn't showing me?   It couldn't have been the woman on the phone because some of the things I was describing she hadn't even found yet!!! 
I'm still wondering if she is in the lumber yard by where they were looking last night, July 8th, 2012?    I keep getting the lumber yard.   
It's SO frustrating at times because I can ALWAYS see where they have been but I'm not always accurate on if they are still there or not. 
I have a paid reading tomorrow and I'm trying to clear my mind so I can concentrate on that one.   Since I'm getting paid I want to get some good results.
I'm just praying they will find Rosie ALIVE!  
I feel I have failed.    I guess it's true that you can't win them all but it is VERY frustrating when so many people are counting on you.  :(
