Okay, so in the last week (about 5 days) Brooklyn has just done a 180 with just about everything. First, she refuses to go to the bathroom when we take her outside (we have a courtyard with dirt in the back which she has happily gone on right when we go outside and I say "potty" for the past 7 months), so we spend SO much time going back and forth and her just looking at us, not going. Even when I know she has to go (i.e. has refused to go for 5+ hours) she won't, then she comes inside and will pee by the back door! Or, last night, she last went to the bathroom at 4, and it was finally midnight when my husband had to stop trying...it was raining, late and we had to get up at 6 am....and she just refused to go (at that point I knew she had to go, but she wouldnt). Then she came inside and went in her crate (huh?!). Yeah, her crate! This is VERY strange behavior by the way, we have had a perfect routine going for months now, she knows when it is time to go to bed, lights go down, we take her out, within 5 minutes we get a pee and poo and when we open the door she takes herself to her crate, gets a treat and plonks down for her sleep happy as a clam. But the last few nights, she just won't go to the bathroom...and I know she has to go. And last night going in her crate was so strange, she has never ever done this (she is 9 months now).
On top of that, she is just resistant to going when we take her out back and it is driving me bonkers. I don't have all day to stand there and take her in and out and in and out. And, she never used to do this in the whole 9 months we have had her (even as a new puppy, she was brilliant). Also, she has started to just go to the bathroom on the concrete vs. the dirt (which she has gone on for her whole life). We have tried attaching a leash, doing the 15 minutes then inside again routine just like when she was little, but to no avail. It is so confusing. She will be standing on the dirt forever, not go, but then walk inside and go. Also the going on the concrete deck is a band new behavior, she always went straight to the dirt before.
So I am confused. Is this adolescence? Is this misbehaving? Is there something I can do? Is there something I am doing wrong? Help!
