That must've been soo scary! I'm so sorry that had to happen to you, but it goes to show what can happen to dogs when their collars are left on. I'm soo glad that they are both alright.

Once, when Sammy was a puppy, we heard him making weird noises in his kennel at night and my mom went down to let him out to go potty. He was hanging by his collar. Good thing we were there or he woulden't have made it. He just had a sore neck and some missing hair.
