Believe it or not, some dog breeds, well-known as Velcro dogs, are prone to follow their owners everywhere.
If you adopt a puppy, you can expect it to follow you everywhere. Basically, the dog gets that habit while still young and follows that pattern throughout its life.
Your doggy will follow you everywhere, including the bathroom, to avoid feeling lonely and vulnerable.
The concept of the dog’s pack excludes any sense of privacy. You are well aware that dogs like to sniff each other even when they defecate. As for your dog, it indeed thinks there is nothing private you can do in the bathroom without its company.
Your dog doesn’t like to be alone, and it can’t understand anyone may want to do something without a best friend. Therefore, you can expect this lovely creature to follow you everywhere, including the restroom.
According to your dog’s opinion, any room can be an ideal place for a predator to hide. Therefore, it is his duty to protect you, who are his beloved being and the best friend, from possible danger.
You can expect that your dog can become curious about your regular visiting the bathroom. Therefore, it may think that something particularly exciting happens there, and it wants to become a part of it.
Since your dog enjoys your full attention, it won’t be happy when you decide to visit a mysterious place such as a bathroom without it.
Since your dog wants to be useful, it may consider its presence in the bathroom while you use it as a way of support.
Often, your dog follows you to the bathroom with a toy in its mouth, tends to pick up a towel from the floor, and offers you the toilet paper. That is its way of showing affection and unconditional love.
