My puppy seems to be barking at everyone these days, all my friends, the mailman, the neighbors. Anyone who comes close to him makes him bark. We have an older dog that barks all the time too, and I think that he may have gotten it from her. How do I fix this? Another problem is that he gets all riled up sometimes and won't let anyone pick him up to take him inside, or he keeps nipping at my feet. Is this a time to put him in his kennel? I don't want to have to use it as punishment though. He's 15 weeks old by the way.
