My 1-year-old still has accidents inside the house
I'll admit I'm writing this while coming off the frustration of just having cleaned up an accident, so please bear with me as this is part vent post as well as seeking advice.
I've got a 1-year-old corgi that just doesn't seem to want to be housebroken. I know he can hold it, because he holds it whenever I let him out of the crate in the morning until I bring him outside, but for whatever reason midday he'll always have an accident. It's been a couple weeks of having accidents every other day now and I feel like I'm losing my mind.
I reward him heavily when he goes outside, I clean up accidents with enzyme cleaner, I've attempted to teach him how to use potty bells but it's been a few weeks and it still doesn't stick. I keep him on a schedule but he'll still go in the house randomly anyway. He doesn't seem to have any signals that I can pick up on, so trying to catch him before he goes has been impossible.
I try to restrict his freedom by crating him, but he's started to incessantly bark when I do and doesn't stop. It's weird though, he seems just fine with going in there when it's time to go to bed, but otherwise he will not stop barking. I live in a townhouse so I've received a number of noise complaints from my neighbors, so I'm trying to be careful with when I crate him to avoid trouble.
I've yet to try the tether method and I think that'll be my next line of action, but other than that I don't really know what to do. I feel like a failure of a dog parent and it's really bringing me down. Please help me?
