Some dogs show point later than others.

I have two dogs from Saulk River.  Both of them point consistently on almost every bird.   Ice as I described earlier has a very refined - perfect looking point.  No he was not trained to point, he just does it.  Based on his hunting style and range, I had someone work with Ice to hold his point longer, but his point is 100% instinct.   Now he holds point all day long with a woa. OK get it, and he flushes.

Buddy, another dog from Jake, also points.   His point is not as stylish as Ice, in fact many times a person who did not know his style, would not know he was on point.   He simply locks up in what ever position he is in when he gets scent.   He could be walking with his nose down low, then stops & locks up.   No foot raise, no straight tail, he just does not move.  Ice is much easier, foot is up, tail is stright.  See a photo of ice as a puppy (10 Weeks) on point.

In Buddies his first season, he was 15 yrds away from a bird, got scent, and locked up. His rear end was going one direction his head and chest were going in another almost like he was going around a corner.  He waited until I moved closer, turned to straighten out then continued a slow staulk to within a few yards of the bird. He locked up again.   I kicked the grass to flush the bird. - Bird almost took my hat off, ( I missed).  Later, I started training him to flush on command.

Both dogs were exposed to birds when they were young.  In both dogs, the point is 100% instint.   

Two neighbors of my parents also have dogs from Jake.  Both of them say, the same. Best dog they ever had. I can't comment on the pointing (they say the dogs point, but I did not see it).
