Slow to Mature - Page 2

I also think this Slow To Mature is used a lot when a dog just doesn't have what he needs to work. Its an excuse. A good pup is a good pup some are a head at 6 or 8 weeks but I personally would not want a working prospect who isn't showing what I want at 6 or 8 months. Drive is drive and for me it needs to be there at an early age.You can enhance drive and increase it if its there but you really cant make it have what genetic did not give them.  Slow maturing physically I can work with much better than slow maturing mentally. If he can work at a year but doesn't reach full size until 2 or 3 does not affect what I need him for.

A lot of very good replies, thanks a bunch guys!

Maturity: Is an  age at which the dog can perform actual work for which it is bred. Physically and mentally. Like Police, herding, S&R, and so on.
 Physically and mentally dog does not need to be totally finished but needs to be able to perform.

Two questions:

1.  Does spaying/ neutering at an early age affect maturity?
2.  How does the rate of maturity impact on bitework training?

Just curious to hear your views.

1. Why to spay or neuter your protection dog?! Yes it may/will most definitely  diminish his maturing process aspecially if done eraly in life.
2. Throws it back considerably and may render the dog as useless for PP work.

 I do not want a slow maturing dog.  Having to wait until the dog is almost full grown to do what I would rather do when he is a pup is not for me.

Any lines out there that produce this for sure ? I want to avoid them like the plague.
