Iv got a 16 week old lurcher , I got him from 8 weeks and I'm wanting to work him! Recently he seems to have got a load of confidence out of no where and has started barking and yelping at other dogs and people! He doesn't do it constantly sometimes we go out and he does it and then other times he doesn't! I'm new to the game but I know a dog that barks a lot is no good for taking out lamping! Do you think iv got a big problem or do you reckon he will grow out of it ? Please help
