I have a dog whose gone back and forth being skittish and doing ok so I'm honestly thinking about giving it a shot... Cause right now she still tucks tail and I'm not a fan of it
the peeing in the water helps for a skittish dog, but if its that skittish it wont solve your problem. you could not feed it for a few days and then hand feed it for a couple months, you could give it a good petting every day, I would definitely keep it in a kennel so you dont have problems catching it up. When you have a loose dog thats skittish, the more you get frustrated trying to catch it up, the more the dog distrusts your intentions, putting it on a chain works too. I think hand feeding meat and taking it on long leash walks would work best
