go from blue to brown. As Charley (6 week old boxer) has blue eyes whilst his littler mates have got brown.

i think its around 8wks!

What shade of blue are they? Clear, bright blue or dark greyish blue?

Bright blue

Then I'd say they're unlikely to ever change. :(

Oh is that bad, might be because he is pure white? Maybe?  <starts clutching at straws>

I dont know about boxers but I am guessing that it is not acceptable in the boxer world as it isnt with dallys from a showing or breeding point of view.  Best check the breed standard if you were planning either.

collies have alot of wall (blue eyes) eyes, & they can all see ok!!!! dont worry!!!!

Im not going to show him, just wondered if his eyes will stay the same, if so he will have the most amazing eyes.

It won't affect his eyesight at all, but it does give a very hard expression (which a lot of people (and dogs) dislike). But the most important thing is the proven link with deafness - even blue-eyed white cats are generally deaf. If you google for "white boxers deafness" there's a lot of info out there. I know you've said he can hear, but how did you test him? Was he on his own or were there other puppies around?

I thought exactly the same but didnt want to sound like the voice of doom. 

My brothers Boxer "Bruce" from Boxer rescue was white and blue eyed and he was deaf they got him at 2 and he was great but he was not socialised properly by his breeder/owner due to his deafness the rescue thought but my brother took advice and he was able to be off lead (in secure spaces) and was very attentive.
But obviously they knew he was deaf as he was adult when they got him.

I tested him away from his litter mates. I distracted him and a friend dropped a bunch of keys. She also, called him and he came to her whilst his back was turned.

I don't want to be a wet blanket, but if the noise was made in the same room as him it's possible for a deaf puppy to detect the vibration or movement of air. If he reacts to a noise made outside the room I'd be a lot more confident.

Emma I think my boxer was about 10 weeks old , she was certainly blue eyed when I got her at 8 weeks.
