I need a little bit of help with a few barking incidents.
The first is that Merlin has been extremely mouthy since he's teething. As a result, he loves to attack my hands. If I move my hands away from him he's taken to barking at me/my hands untim I either comply by returning them to a spot where he can get to them or until I get up and either move across the room with my back turned or until I leave the room completely. Usually, when I get up and turn my back on him he stands and barks at me for a few seconds before giving up. I try not to reward him or reinforce him in any way when he barks at me, but it doesn't seem like he's really getting it. I need some suggestions/ideas on what to do about it.
The other instance of barking (and making lots of excited puppy noises in general) is when I get ready to take him out for a walk. Usually he just makes lots of puppy noises, but he goes in to a barking frenzy when he hears people in the hallway as we step out of my apartment. At first I thought that maybe it was because I was getting him too riled up before we left by asking if he wanted to go for a walk. I've tried cutting up most of the "routine" I had established (putting shoes on, getting my keys, putting his harness and leash on), thinking that might cut back on just how excited he would get prior to actually going out my apartment door, but it hasn't really helped. He also makes a lot of noise on the way down in the elevator. Is there anything I can do to help him get past this noise-making stage? I know he's still a puppy, so I'm not holding him to extremely high expectations, I would just prefer if he could be a little quiter on the way out. I think part of it is that the door to my apartment has a more private entrance than some of the other apartments (it's around the corner in a nook with one other apartment) as a result, Merlin can hear anyone moving in the hall before he sees them (hence the barking?)
I'm considering not taking the elevator down for a bit and just using the stairs until he's a little less barky. There's a stairwell almost nextdoor to my apartment.
Lastly, he loves barking at people who are near him. He's done this on the elevator, in the hallway, etc. I think it's his way of asking for attention, and I think the only way to solve it is to ask them to ignore him either completely or wait until he's sitting quietly to pet him, but is there anything more I can do? Yesterday I was on the elevator with a mom and her toddler. She was holding the toddler and talking to me while also talking to Merlin in a baby-talk voice. Well, he barked and the toddler immediately burst in to tears... Talk about embarrassing.
I've done a lot of apologizing lately because of how much barking and noise he makes.
Also, I'm not worried about noise complaints from my neighbors, our walls are pretty thick and most of the building's residents have dogs. I'm just interested in teaching my dog how to be polite in echoing hallways, elevators, etc. Barking is also not my preferred method for him to get my attention.
I'm sorry if this is rambling, I just don't really know how to go about handling this and would love some advice, tips, etc.
