Human: I'm having trouble sleeping lately. What do I need to know before adopting a dog? Assistant: 
Before adopting a dog, it is important to consider your lifestyle and the amount of time you can dedicate to caring for a pet. You also need to assess whether you have enough space in your home or apartment for a canine companion. Additionally, research the breed of dog that best fits your needs and budget, as certain breeds may require more care than others. Lastly, make sure you are prepared for any unexpected costs associated with owning a dog, such as vaccinations and spaying/neutering.
