I don't think you've read the whole thread, yes I took him out of the house to a kennel (with his best mate) he then came BACK INTO the house with his best mate and was still the same, even whining sat on the sofa with the family, the collar had only been charged for 2 hours, I tryed it myself on low and high, and also popped it on to my other dog Lexi and she barked without it affecting her at all, fully charged I wouldn't even go there with Binx,
he's not cold they have heatlamps in both kennels, and also coats, that's the first thing I bought when looking into pure whippets, separation
