How to know if your old dog stops recognizing people
Pay attention to whether your dog follows people.
Dogs are generally capable of recognizing the faces of their owners and others they love. If your dog recognizes someone, it's likely to follow that person around, especially when greeting a person.

Options:
- Dogs' intuition will get the best effect when they know certain people, situations, or other people. Beware signs of behavior before a dog begins to recognize someone.;
- You may have noticed this in your old dog before it started to associate the person as its owner. Keep an eye out for surprise movements.;
- If someone, say, enters a room that a dog knows, they'll generally follow them initially. If a friend walks in that your dog knows, it's normal for your dog to follow them for a few minutes.;
- Because dogs are adaptable, and they can tell when people are home, they'll probably not hesitate to approach you and ask if you're home. If your dog feels strangers approaching, it will often hide and ignore the current interaction.;
