However, there are a few ways a dog might *appear* to untie something:
* Chewing: If the knot is made of something chewable, a dog might chew through it, effectively "untying" it.
* Pulling: A dog might pull on a loose knot, potentially causing it to unravel.
* Accidental Loosening: A dog could accidentally step on or bump a knot, causing it to become looser.
It's important to remember that dogs can't intentionally untie knots. If your dog is chewing on a knot, it's best to remove the item to prevent them from ingesting it.
