The proper training of dogs warrant treats. The better the treat the better the result so to say. There is this boxer in my house that thinks treats are conspicuously conspiratorial ways of making her do things she normally wouldn't. On the other hand, if, instead of a treat you use a ball - as I might have mentioned - she's willing to do anything.
Happily skipping along towards the field where balls are thrown and hunted.
Sitting as pretty as can be, begging to run after said ball.
Jumping on command for me to try and catch her picture.
Guarding her prize in the shadow of a trimmed hedge, rather like a dragon on her hoard.
There we are: The training and rewarding of blackish boxer bitches.
