My husky mix! Got her 7 weeks ago and she has been the best!

Balto loves his girl Starr!

My wife and I adopted Apollo 4.5 years ago. He turns 13 this week and has trouble getting up the stairs to the second floor where we live. Apollo weighs 70 lbs and has been getting Librela injections for several months. How have others in such a situation solved this dilemma?
