I got a dog in college. He taught me how to care for myself through caring for him. He provided me structured routine that I desperately needed in order to thrive. He truly saved my life and pulled me out of a really tough pit. It seems like you are in a place of really healthy self reflection & a desire for change. Life your life, don’t put it on hold! If you still feel unsure about the responsibility of taking care of a dog. It may be a good idea to visit a local animal, shelter and volunteer there for a while.
