I forgot to update you guys on this issue. I will say Harley is a very sensitive girl. If I'm outwardly stressed and upset, she will vomit and hide in the bathroom. As for the peeing, I finally put it together. No diseases of that I'm aware. She's a submissive pee-er. That time she peed all over the kitchen, when I thought about it again, it made sense. My friend had went to pick her up and that scared her, so she ran away peeing herself. The other time, I can attribute to me probably saying something harshly towards her. If I walk up to her and she thinks I'm mad, she pisses herself. It's hard to deal with sometimes. Now, recognising the problem, I'm hoping to slowly fix this issue. She's a really submissive dog in general. When she goes up to people, she scared and wags her tail in such a way, she's trying to tell them she isn't a threat. (If that makes sense). Thankfully, she has not peed herself while a stranger tries to stroke her.
I don't want you to think that I beat her or anything like that, lol. She's been like this since the day I adopted her. I always try to be gentle with her. Obviously if she misbehaves, I have to correct it, and I try to do so in the most gently firm way w/o her peeing herself.
