The purpose of this design is to promote the Senior Sniffer Sanctuary as a nonprofit sanctuary for senior dogs. The advertisement aims to raise awareness about the sanctuary and the services they provide for senior dogs. The intent was to share these services with dog owners who have aging dogs that need special care during their final days. The target audience includes dog owners who may have difficulty caring for their senior dogs during this transition. 

For the design elements and principles, I used contrasting colors such as orange and black to help highlight the main message and emphasize the large image of the dog. I used alignment to create a balanced look and grouped related information to help the viewer understand the provided information.
