Just looking for a bit of reassurance. I feel like we've taken about 10 steps backwards with our little 15 week old cocker.
When he came to us he seemed to pick up the toilet training really fast! I was heavy on the praise when he went outside, and tried not to make a fuss when he had accidents indoors. He was really good and would actively go to the back door when he needed to go. In the last week or so he's just having so many accidents indoors, and getting him to go outside is a struggle. For example this morning I stood outside with him for 20 minutes (i have to stand out there otherwise he'll just follow me back in or bark at the door until I let him in). He did nothing. We were back inside for 5 mins, I turned my back to do something and he's weeing on the floor.
Also night times are becoming a struggle. We have a stairgate on the dining room so he has run of the dining room and kitchen overnight. He has a crate with bed in, with the door open, and a separate bed which he uses during the day. He has a basket of toys. His water is always full. He was going okay sleeping about 4-5 hours, I'd go down and let him out when he wimpered, sit with him to settle him then he'd wake up at about 5amish. Recently he's been sleeping for about an hour then he'll cry, wimper and bark at the gate. I keep going down, settling him, come back up and as soon as I'm at the top of the stairs it starts again. 3 nights ago it was 2am, I was really tired and fed up so I put his bed upstairs next to me because I just wanted some sleep. I know I'm probably my own worst enemy for doing so but I work full time and I was just shattered and gave up. Now all he wants to do is be upstairs. We can't even settle him at all until he's upstairs. Last night, for the first time ever he managed to jump and pull himself up into my bed. I put him straight back in his own bed but he kept jumping up. Eventually he actually growled at me when I tried to move him from my bed. He's never growled at me before. I felt awful. He was really tired, he had hardly napped last night at all and he'd been for a walk and doing zoomies for about an hour. I wonder if the growl was because he was overtired and just wanted to be left? But I don't want him in my bed.
He's also quite nippy at the moment. He keeps nipping at us when playing. I've taken to putting him behind the stairgate for 5 minutes everytime he takes it too far and nips one of us so he knows that as soon as he bites that's the end of playtime. Am I doing the right thing?
I just don't know what to do, or where I'm going wrong. Should I be worried that he growled at me? I don't understand how we made so much progress and now it feels like it's gone backwards. What am I doing wrong?
and just as we make progress with it, another dog gets too close to her and it sets us right back. Google the engage disengage game, it’s really helpful.
so I think that really helped!! We have only recently took our pups crate away (she literally loved it lol) Now they are like a wee duo 
). So I put him in the bed, locked crate and turned the lights off and left him to see what he’d do. No crying yet. Leaving him for 10 minutes and then I’ll go get him but I think that’s a good sign
our girl was an angel but a tad overwhelmed I think, she regressed a bit with toilet training etc but I don’t think that’s her fault.
