I don’t know why I won’t let you buy a dog. This may depend on local laws and regulations, or your personal circumstances, such as whether you have enough time and energy to care for your dog. It could also be that your residence is not suitable for keeping a dog, or that your health cannot tolerate a dog. If you want to buy a dog, it is recommended that you first consider whether you have enough resources and ability to take care of it.
Dogs need to be cleaned, fed and exercised regularly, and they also need to receive regular veterinary examinations and treatments. Also pay attention to comply with local laws and regulations, such as those regarding dog breeding, keeping, and access to public places. All in all, raising a dog is a huge responsibility that requires careful consideration and preparation.
