need help Evaluating......

[MEAUXTIVATION]

I got a couple I evlauated: Question? Can a dog go from hot to cold. Meaning loose interested before they are ever started. Got a buddy telling me that I'm waiting to long to start them. Also!!!! if I wait to long do you think I have to be more patient when it comes to starting up..

Your buddy is telling the biggest bs I ever heard. If you have the patience to start them at 18 months to 2 years or even later, that's great. Get this facts straight also: "hot" doesn't mean started. It just means "aggressive behaviour" but the dog could be cold.
No interest in fighting ( on the street, or on the yard) does not mean "cold", dog could be hot as fuck when put to work.

Most dogs will let you know when they are ready...

Nut said it perfectly, a dog that portrays a certain behavior is just that behavior it means nothing. Only way to evaluate a dog ability to perform is to give them that opportunity.
