Hold on to your hat anthony! Saying you may get rid of her due to simple behavioral issues is going to get some hot responses!!

I won't go there, and I won't be much help in the training area, but my suggestion would be to spend one on one time with the Rottie. Take her out by herself and make sure she does both 'jobs' before she is allowed back in the house. Then bring her back in and take the other dog out........or have DW
walk the pug while you walk the Rottie.

What was her schedule before the new pup? Was she fed first and then let out or was she let out, fed, and then let out again? Is she getting less attention than before?
My gut feeling is that her schedule has changed since the new pup.........and she's confused.

We experienced this when we took care of our dog's fav playmate a few weeks ago. Both dogs are completely housebroken, healthy etc. but first morning our pup had an accident. If they went out together they'd get too distract and focused on each other and not get to 'business'. Just like little kids would get back inside calm down and get desperate to go back out again.

The solution was separate, SUPERVISED (not from the window, but outside) potty breaks, with a play time together outside after everyone did their stuff.

Also, consider a vet check just to rule out a behavior change related to a health problem.

A new dog is a big transition for a single dog. Your rottie deserves some adjustment time and especially some one-on-one time. It's easy to coo over the new arrival and leave the ol'dog behind. I hope a solution is found, it seems terribly unfair to give up on a 2 year companion who is probably just having a hard time adjusting.

Another thing to consider...

You've stated the new dog is a lap dog. Therefore, you've unintentionally elevated the new dog to a higher status than that of the rottie. In the pack order world of dogs, if a dog is allowed to do things that the Alpha dog (you) does (e.g., sit on the couch - which to the rottie, your lap is the couch), then they're equal (or more equal?) to the alpha. So your rottie may be acting out due to the new order in the house.

Also, she could be acting out for your attention. Don't make a big deal out of her going in the house unless you've actually caught her (then, just yell no and take her out to finish her business). Don't even let her see you clean it up. And of course, praise her for going outside. It's potty training all over again. :-)

I'm certainly no expert, just food for thought.

As others suggested, spend one-on-one time with the rottie, take them out separately, let her know she's special, and let her know the new dog is not alpha to her.
Good luck.

What Jmzms said makes complete sense. It's definitely a behavioral thing and your rottie is acting out. And the poster's suggestions are exactly what I would've suggested - you may just need to "train" her again...in a sense. I think in time things will go back to normal. If not, I would hope you'd do all you could to fix this situation or try to understand it better (I wouldn't consider it the worse situation...it could be worse, like aggressive behavior). I have to admit, I'm a little shocked that you'd even consider giving up a dog that you and your family "love to death".

Anyway, you'll definitely get a bunch of suggestions from forum members - try them all if you have to! Something will work.

By the way, how long have you had the pup for?

I can't believe you would even think of giving up the Rottie who you love and have had for two years. The little dog should go if anyone goes. But hopefully you will be able to correct this behavior issue.

I also agree about elevating the older dog to a dominant position in the house.

When our dog died, and we brought in a new companion for Ricky, we intentionally always went to Ricky first, and said so.

Ricky, let's go outside. Our pup learned to "wait for Ricky" as he would walk proudly out the door first. When we fed them, we would say Ricky eats first. Actually we only set down his bowl first, then fed the pup. Even now a year later, we always let Ricky go first and make a big deal of it. Blaze knows nothing else. Ricky leaves and enters the house first. He eats first and gets in and out of the van first. We brush him first and pet him first. Even if Blaze runs up to us to the gate first, we often will stop petting him and pet Ricky when he arrives.

All of our dogs are lap dogs. We just sit on the floor. In time when the older one feels more comfortable, the little dog may be a more exclusive lap dog, but for now, I would sit on the floor, and pet the older one first.

We keep our dogs in the most popular area of our house, so we go to them. They are rarely alone, but we do not allow them into our living room or bedrooms. Those are off limits, so we don't have dogs with us 24 hours, and we sleep without dog dander since we are very allergic. Therefore we can easily declare that Ricky is first in whatever we do.

I don't think you will have a problem after a couple of weeks. If you do, you might consider discussing this with the Vet to see if there is a mild medication you can give your older dog for anxiety.

One more thing - when we were walking our dogs, Ricky used to always poop. We would scoop it up, and walk with it. Once my husband hurt his back and had to stop walking with us for a couple of weeks, I quickly got tired of this process. Before our walks I would take the dogs out as usual, and I began telling Ricky to do his business. He would walk inside, and I would call him out. I kept telling him to do his business, and he began doing it. Now he understand that he must do it before we walk. We haven't needed the bags for about 6 weeks. It may be that your dog is performing for you in a more dramatic fashion than the pup can do. You might keep the dog outside with you (and not the young dog), and insist that he poops before he comes in. Even give him a treat if he performs for you. We all know that a dog's brain is wired completely different from ours.

How about taking the rottie on some walks? That would give him some one-on-one time with you, and exercise stimulates the bowels so she would most likely poop on her walk.

5-10 minutes in the yard isn't enough, especially with the distraction of another dog. When my dogs have their morning outing in the yard instead of a walk, we spend about 15-20 minutes out there (hey, it's cold up here!) and I throw their balls/frisbee to get them moving.

That actually made me sick to my stomach to read that you might give up your rottie because of this problem that YOU probably created. I think the suggestions given are good ones. I have had dogs that have had problems but I worked through them and with them but never ever did I give up a dog because of the problem. In my opinion once you get a dog it is yours to love and take care of for the rest of it's life. Angie

I agree with Angie. This is a behavioral problem that you can fix, if you want to put in the time and effort.

I have a 9-year-old dog that poops in my fully carpeted apartment due to bowel incontinence from medical issues. Well, my choices are to either put a diaper on her or to clean up the poop. Giving her away is not even CLOSE to being an option. I clean up the poop...
