I need help with my dog!! 🐕

Hi guys I didn’t have anywhere else to post this so I thought I’ll post it here.

Okay so I just got a new puppy and I never had a dog before, so this is new to me. She’s adorable, playful, and a fast leaner, but when it comes to doing her business outside, lets just say it doesn’t end well, I mean she always pooping and peeing everywhere, and I try to discipline her, but I feel like nothings working.. btw I’ve had her for a week, and she’s three months old. I know she’s still a baby, and I still love her, I would never give her away for the world. So I posted this because I wanted to know if any of you have a puppy or been threw this cycle with your dog. if you have, please leave helpful comments down below. I would really appreciate it. thanks!
