Wanted to make sure, thought it was a typo, that is my great nieces name. I had heard of Brook before, but, never Brooklyn until she was born. I have noticed puppies sometimes can be like little kids. You know how little kids after they're potty trained, sometimes forget to go to the bathroom, until it's too late?? I'm sure this is probably what she's doing. But, she could be upset with you about something too. My mom got a dog when it was 11 mos old. The first time she peed on moms bed, mom didn't say much, as she thought she was just adjusting to a new home. The 2nd time she did it, mom really got on to her, she said the dog probably thought she was going to kill her, but, she never did pee on that bed ever again. Now shes's 14 years old, and the best little dog..You really have to change your tone with them when they do something wrong. My grandma always had a dog(and this is no lie) housebroken in 1 day. Sure wish she was still around, would have sent some of mine to her...
