Bruno is only a year and half old but I hear so many stories about doxies having spinal cord injuries and it's really scary. I read an article online that said to not let your doxie use stairs or jump. I never let Bruno use the stairs...I carry him up and down. He doesn't like them anyways. But he always jumps off of our bed. He has a set of doggie stairs to get onto the bed but jumps off when he wants down. I guess it's pretty high for a little doggie but he doesn't seem to care. Should I be worried?
