If your dog sniffs you too much, it might be an indication that he needs more exercise or playtime. But there are some things you can do to get him to stop sniffing you. 1. Make sure your dog is healthy. If he has any health issues, such as respiratory problems, allergies, or diabetes, you should see your vet before trying to train him out of the habit. 2. Try playing with him while he's sniffing you. This will distract him from the behavior and allow you to get away without having to say anything. 3. Train him to recognize when his owner isn’t nearby. Teach him to associate the sound of your voice with treats or toys. Then when he hears your voice, he'll know not to start sniffing you again. 4. Play a game with him. When he starts sniffing you, try giving him a toy or treat so he knows what happens next. Play with him for a few minutes until he stops sniffing you. 5. Be patient. It takes time to change habits, especially if he's used to doing something on a regular basis. With patience, though, you'll eventually succeed in getting him to stop sniffing you. 6. Keep quiet. Don't talk or make any sudden movements while he's sniffing you. His hearing is better than yours, so he may think you're talking to someone else or moving around behind him. 7. Remove yourself slowly. When he starts sniffing you, move away a little bit at a time. He'll soon realize that you aren't going to hurt him and that he shouldn't follow you around anymore. 8. Reward him. Once he realizes that sniffing you doesn't mean anything bad, give him a reward like a tasty treat or affectionate petting. This will reinforce the idea that he should only sniff you when he wants to. 9. Use a different location. Move him to another room or area when you want him to stop sniffing you. A new place will help him forget about the old one. 10. Start training early. If you wait until your puppy is older, you'll likely be too frustrated to continue. Instead, start training early so you don't have to deal with this problem later. 11. Don't ignore it. If he keeps sniffing you even after you've tried everything above, call your vet. They can diagnose his condition and advise you on how to proceed. 12. Talk to your vet about it. If nothing seems to work, bring your dog to the vet. The vet can take blood samples and do tests to determine why your dog is sniffing you so much. The vet may need to perform surgery to remove excess skin or glands from his nose. They may also prescribe medications to reduce itching or irritation. 13. Keep him comfortable. Dogs with sensitive noses often suffer from excessive sniffing because they feel uncomfortable due to allergies or infections. You should keep your dog clean and free from allergens to decrease his discomfort. 14. Change your scent. Some dogs are very good at detecting scents. If your dog is constantly sniffing you but you haven't done anything wrong, maybe you just smell differently. Try wearing less cologne or perfume, and avoid using deodorant. That way, you won't offend him. 15. Watch his body language. Sometimes dogs get into the habit of sniffing certain people because they sense that person is safe. They may look at you as though they expect you to pick up where they left off. To break this habit, watch his body language carefully and act accordingly. 16. Consider medication. There are a number of prescription drugs that can help with excessive sniffing. Talk to your vet about these options if nothing else works. 17. Talk to him. You may find that your dog is simply curious about you. In this case, you can encourage him by talking to him and providing attention. Playing fetch or tug-of-war with him can also help to keep him occupied.
