Thank you for the replies and the info.
The dog may be friendly, and it may not be. I don't want to find out with the safety of my family.
You have to realize this dog is not the size of a normal dog. If it stood on its hind legs it probably be taller than me, and easily much larger than my wife. I talking at least 70 lbs+. I have been working a lot lately, and dead tired. And, to be woken from a dead sleep with the wife screaming that the dog was on our property was very unsettling. Luckily, the dog was not mean, and pretty much listened to what I was telling it to do, which was to 'go home'. But, with an animal of this size, I don't care if it is naughty or nice, if it decided to attack there would have been some serious injury.
Here is a pic I found on the net. This one is fatter than the one we encountered, but the height looks about right. Chest high for me..

If the dog was mean, and I had to bat, shoot it, or whatever, what charges would I face? Knowing this state I probably would have been up sh_t creek.
After my immediate and unequivocal reprimand, back door neighbor erected a wooden board, thus blocking the access the dog had to jump over the fence.
I just hope they wise up.
