Why is my male dog suddenly marking inside after being house-trained?

Updated On September 23rd, 2025

Pet's info: Dog | Pembroke Welsh Corgi | Male | neutered | 9 months and 10 days old | 28 lbs

I’m getting very frustrated. I taught him how to use puppy pads, then I taught him to go to the door to tell me when he needs to potty, ever since he started lifting his leg, he just goes where he pleases & I correct him several times a day but still does it. He potties outside very nicely. I tried turfs, sprays & more but he will wants the puppy pads& I took those away long ago. I even trained my female and she uses the brilliant pad. He looks me straight in the face too. He’s too old for this.

Hello, I'm sorry to hear you and Asher are having some road bumps in the house training process. I'd recommend reading through Sophia Yin's potty training guides. Some dogs are easier to train than others. Here is a link: https://drsophiayin.com/blog/entry/what_to_do_when_your_puppy_potty_training_plan_fails/ I hope this is helpful. Thanks for using PetCoach.
