The context of the following conversation is Sasha wanted a dog, but was not confident in controlling it.:
Sasha says I have wanted a dog for so long and I think I finally found the right one..
The friend responds Why don't you go ahead and get it then?.
Sasha responds I am just worried because it's a German Shepherd and I am worried that I won't be able to control it..
The friend responds I took my dog to an obedience school and I can give you the number if you want it..
Sasha responds I know it's important for the dog to know I am in charge so that's probably a good idea..
The friend responds I think you should call and talk to my trainer because I think you will be fine with your new dog..
