If your dog has not been exposed to other dogs or humans, he may feel scared or uncomfortable and be reluctant to go outside. Dogs may be reluctant to go out due to physical discomfort, such as joint pain, digestive problems, etc. Some dogs may be reluctant to go outside due to separation anxiety, phobias, or other psychological issues.
Dogs may feel uncomfortable or uneasy about the noise or smell from the outside world, and thus are reluctant to go out. Some dogs may not like walking in unfamiliar places, such as noisy city streets or wilderness mountains. If your dog is unwilling to go outside, it is best to rule out any medical problems and consult with your veterinarian to see if further diagnosis and treatment is needed. At the same time, gradually cultivating the dog's adaptability to the outside world, such as slowly increasing the time spent outside and contact with other dogs and humans, can help the dog gradually overcome this problem.
