We adopted a 3 yr old female pug last month. She seemed to be potty trained and did her business outside until now! All of a sudden for the past few days she has been pooping and peeing in the house.
Just a little background: When we got her she was really aggressive and we kept redirecting her aggression with toys and chew's. Last week however she was uncontrollable and all my fiancé did was yelled "NO". Since then she is weird around him. After this incident I also noticed her hair shedding A LOT. I want to say more than before! She still loves to play with him and all but when he is standing up she walks away with her tail curled down! I have a feeling she remembers his NO every once in a while.
She eats well and is a healthy pug except this sudden behavior! PLEASE HELP! I love her but my fiancé is losing patience!

You need to start from the beginning with her, be consistent, lots of praise, no negativity as it will only make matters worse.

Take her outside, use a word for potty, like potty time etc. Say the word over and over and when she goes potty, tons of praise. Go nuts with praise, good dog, wonderful dog, pet her, even give a treat at first.

Take her out often and repeat the above.

If you see her start to go inside, stop her, take her outside repeatedly and do not go back inside until she's pottied. Then more praise. Before long she'll ask to go outside, or you can open the door, tell her to potty and she'll go.

If she was trained before then this shouldn't take too long to reinforce.

Now for you fiancé. Dogs don't understand yelling. You'll never see dogs yelling at each other in the wild or in a home. It's not part of their DNA. When you yell at a dog the only one that understands why is you, the dog is just afraid and unsure.

The shedding sounds like nerves. Pugs can be very skittish and it sounds like the incident with your fiancé has done exactly that, made her nervous and skittish.

Thankfully dogs don't hold a grudge like people do. Do not be overly protective of her or feed on her fear. Everything is normal, it's all good. Start from scratch and get your fiancé involved with her training, just make sure he understands that yelling or hitting a dog is not okay, not if he wants a bond with this dog.

Let me know how it goes and tell the fiancé to be patient. :)

Good luck and congrats on your new addition.

You've only had this dog for a month. She is still adjusting to her new life, what she can do and what she can't do. This can be very awkward for her, same as it is for you. Not knowing the dogs history, ractions and what - not.

His firm NO could have very well reminded her of something bad in her past. I work with a lot of rescues, a lot of them are abuse cases. Sometimes, a harsh tone of voice is all you need, some need a little bit more reinforcement.

Your dog is what I would call a "soft" dog. Meaning, very little correction needs to be made to get your point across... Almost as if your dog gets "hurt feelings" after a correction is made.

You're going to run across that problem more then once. Like I said, right now it's that awkward stage where neither you or the dog know what to do.

A really good way to re-establish trust, or even gain trust, is obedience. Nothing fancy... just very basic sits, downs and stays. Also introduce "watch me". "Watch me" is a very good focusing command. It prepares the dog for what comes next.

Her pooping and peeing in the house could be fear related, but seeing as how she is POOPING in the house, I doubt it. Being a rescue dog, I'm not sure if she lived with a foster mom or not, she could very well have "forgotten" how to be house trained. Dogs that go through traumatic changes will replase quite a bit. Being bounced from whatever home she was at in the first place, to the shelter, to the rescue, maybe to the foster mom and then to your house is very traumatic... Even if that did happen over a couple of months, its still very stressful.

This is where a crate is very needed. If you cannot watch her, put her in her crate. If you leave, she gets to go into a crate. Crates keep good dogs good. If she is pottying in the house when you leave, every time you come home, you're going to be upset with her and it'll be a negative experience for her, and you too. But, if she's in a crate, and you come home to a clean house, you're going to be happy to see her, which will give both of you a posetive experience.

If she sneaks off while you're home and does her business in the house, tie her to you. She cannot sneak off, you'll learn her signs of needing to go out and you'll be able to correct any mistakes. If she does make a mistake in front of you, you're going to want to startle her with a very harsh "eh-eh" then immediately do the dash to the door with the very happy "outside" command. Watch her potty! Praise her. Go inside, and clean up her mess. I never allow my dogs to watch me clean their mess up. Don't make too much of a fuss over it. It happened, you corrected, your praised now move on. If she's already house trained, she'll get it real fast!

As for the aggression? I'm not quite sure what you're talking about. Was she very mouthy? Young dogs typically do mouth. They push their limits to see what they can get by with. From what I read, it does appear that you have that under control.

All in all, to avoid any more issues, sign up for obedience class. I wouldn't recommend Petsmart or Petco, they both have very little knowledge about dog training beyond the company manual ;) But signing up for training will help you understand your dog. You'll make mistakes, she's old enough where those mistakes won't effect her. She's a "soft" dog, so you are going to learn what types of corrections you can and can't do.

Good Luck
