from the little i know, skinwalkers leave a foul stench wherever they go. unfortunately blessing a house doesnt do anything, since skinwalkers are technically humans. really keep an eye on the dogs ig. btw you call your dogs to come in from the outside right? cuz thats how the sw probs got invited if it even is one. (also never whistle at night, and dont respond to any whistling you hear anytime of the day. if you find bones at the front door, dont goddamn touch them.) it may not be a skinwalker, but its best to take precautions. all you can do is keep your eye on the dogs
