According to the vet, it's going to take a while to fully leave her system, but it shouldn't have done any permanent harm. It explains her inexplicable terrors and periods of jumpiness followed by somnolence when she first got here, the bruxism (to the point she's worn her teeth down), the nervous licking of EVERYTHING, and her timidity in general.
I don't have any problems with people getting high, but I have a real problem with people doing this to their animals. For dogs, this stuff is a neurotoxin. They're not high, they're disoriented and going through violent mood-swings. They are not feeling good and chilling out. They probably can't use their legs properly or balance. They're not relaxing. They're sedated. Eating it, like in a brownie or if they get a hold of a roach or your stash, is dangerous as heck if not treated because they can get to the point they can't regulate their own body temperature or drink properly without choking.
She's getting better every day. I'm starting to see the playful side of her, but the legacy of that fear will take longer to go. She's timid around all strangers, but terrified of men. Once she trusts you, she's a real charmer. Until then, she is literally cowering belly-down on the floor, trembling visibly.
She flat will not leave my side voluntarily, even for people she's known longer and generally likes enough to be playful with, as in my daughter. My daughter watched her while I went to the grocery store last night (because if I leave her home alone even long enough to go to the mailbox she gets so stressed she vomits). When my daughter tried to walk her down to her house, Cleo went joyfully with much butt-wagging and licking as far as my car, then flat refused to go farther and dragged her back up the hill to my place to get me. I had to take her there and then leave her whimpering with my daughter holding on to her at the door.
I don't know why she trusts me like this. I got some story that before they got her she lived with an old lady, and maybe she's associating her with me. But since that comes from the person who told me she was only 2 (she's five) I don't know and I have no way of really knowing for sure. I got her a harness that fits; the one that came with her was way too small and was wearing her fur off and has been that way long enough it's left dents in her skin like the ones where my glasses go over my temples. Have to do a harness because she can slip a collar at will due to the muscles in her neck (she's a boxer). She's apparently never seen a vet so we need to do shots and I need to find out if she's been fixed.
It's infuriating. It breaks my heart to see her cowering on the floor because my son came in, and to see her inching towards him when he hunkers down to reassure her. I'm having to teach her how to play with toys. She literally doesn't know how.
tl;dr: Smoke all you want yourself, but DO NOT GET YOUR DOG HIGH.
