I really don’t want to give up on training but it’s been tough. I just need some advice on how to go about this.

So I’ve had this dog for about a year and when I got her she was like 4 months old. She was found in a box by my old coworker and she asked if I wanted her and I said yes. Maybe I should have said no but that then made 3 dogs in a house with plenty of room and the other 2 are small dogs too.

For reference the two already in the home one is a (4 y/o) terrier mix and the other a (10 y/o) bichon mix. The 10y/o is trained well enough but for the most part both dogs are potty trained, walk great, listen, and I did train both when they were adopted. I was also younger and had all the time and the first dog was a breezy second dog got lucky and also my sister’s pup.

So getting to the point of this story/question. This 1y/o pup she’s high energy, she’s smart and picks things up quick but not the potty training. It is also my fault my sister helped out taking care of her when I was at work and she wasn’t training or keeping up with it. She just kind of let them do whatever and the pup followed the other two dogs.

I have now moved into an apartment with the 10, and 1 y/o and it’s been rough. I’ve been walking them early in the morning when we wake up. I walk them as soon as I get home and after they eat and before bed. Sometimes even extra just so they can go pee those are usually short walks. She still has managed to pee in the apartment, on my bed, the carpet, and on the floor and she even went number 2 inside after the walk. How do I train her and I play with her too it’s not that I’m neglecting any it’s just the 10 y/o is so chill he loves his walks and cuddles and she’s the opposite. I can play fetch with her all day. Idk what should I do or how do I tackle this.

Also during the day she watches dog tv from her kennel, she also loves to chew on things the amount of socks and slippers that have seen better days.
