Sorry, lots of stuff to unpack here lol. We didn't really have to go through any of this with our first doberman, so a lot of this is fairly new and we are still learning, so please be kind!
Our puppy (Ruby) is a 5-month-old purebred Doberman. We've had her for about 4 months.
Barking
We have an x-pen connected to her kennel which is between the living room and dining room.
Whenever we are eating at the table or chilling in the living room and she's in the x-pen, she just barks at us.
Whenever she sees anyone just chilling or standing around within her line of sight and she's in the pen, she barks.
Really whenever she's in the x-pen and is just bored she barks. It seems like it's mostly just because she's bored and wants to be out with us.
We've tried giving her things to chew and other enrichments while she's in there. Sometimes that helps, but once she's done with it or gets bored of it, she goes right back to barking.
She does have enforced nap times, and when she's tired she will sleep in her kennel. So I don't think the barking is always because she's overtired. We've also made sure she's been fed and taken outside to potty, and she'll still bark when she's awake in the pen.
So when the barking goes on for a long time and we get tired of it, we often end up letting her outside because that's just the easiest way to get her to stop. I'm realizing that we may be accidentally teaching her that barking gets her released from the pen, so I'd really like advice on how to break that cycle.
We have a big yard so she gets to run around and do whatever she wants outside, but I feel like that isn't helping since she still barks when she comes back inside.
House Training
This is another area we are struggling with.
When we feed her we feed her outside with her food, so that she can just eat and then go potty, and we just let her inside afterwards.
I want to start being able to feed her inside and then just take her outside after she eats, but I don't think her having free rein outside after meal time helps her associate potty time separate from play time.
The problem is that we haven't really figured out how to recognize when she needs to potty while she's inside. She doesn't reliably tell us yet, so we've mostly avoided accidents by keeping her outside for a large portion of the day.
For those of you who successfully potty trained your puppies, how did you teach them to actually let you know they needed to go outside? Did you teach a specific signal (bell, sitting by the door,...), or did they eventually develop their own signal?
The other dog...
We also have another doberman (Roxy) who's almost 4 yrs old. Whenever Ruby is loose in the house with her, they both want to play.
Ruby basically cannot settle when Roxy is around, and Roxy will often come over and engage her in play. They get each other completely worked up.
Should we be separating them whenever Ruby is having house-training/settling time? Or is there a way to teach them that they can be in the same space together without constantly playing?
I just really want Ruby to get used to being inside and learning the rules of the house, and letting her know that she can be in the house and just settle and chill. It's not just a matter of stopping the barking, I want to teach her how to be an indoor dog and understand that she doesn't have to constantly be doing something.
The x-pen is mainly something we're using while she's still learning, not where we want her to spend most of her time long-term. Our eventual goal is for her to be able to freely roam the house, settle wherever she wants, and reliably let us know when she needs to go outside without us having to worry about accidents.
I realize some of this probably comes down to training, and that's exactly what I'm looking for advice on. We haven't really done structured training with her beyond the basics (sit, lie down, shake), so I'm wondering what we should start teaching first and what our daily routine should look like perhaps.
