Dog Doors - are they good or bad?

Let’s get straight to it - I am generally against doggy doors. 
​
And here is why:

By using a dog door, you are giving up your authority to regulate your dog’s whereabouts. A dog door allows the dog to go in and out whenever it pleases the dog. The idea behind installing a dog door is generally a great one; now, the dog can go to the bathroom whenever they need to go and do not need to wait for the person to open the house door. Here is the crux with that: most dogs will use the dog door for more than just bathroom breaks. They hear a noise outside and run out to bark at it; they hear the neighbor's dog being outside, so they run out to bark at it or fence-fight. They get bored inside, so they look for entertainment outside, which results in digging in the yard, eating sticks, dirt, and rocks in the yard, and destroying the yard because it is fun. They run outside because they grab an item (like clothing, towel, or pillow)  that they aren’t permitted to have and are trying to hide it. They try to bring items inside that are not desirable inside the house, like sticks, leaves, mice, and gofers they caught or dead animals. Many, many, many reasons why I am against the use of a doggy door. The only time I would recommend using a doggy door is when you have a senior dog who is getting incontinent and, hence, needs to go to the bathroom more frequently but already knows that being outside is for taking care of business and not engaging in nonsense activities. 
So, next time you are thinking about installing a dog door, weigh their pros and cons very carefully.
