I'm 68 with a herd of health issues. My service pup is 8 yrs, 50 lbs, with rear right leg arthritis. We live in the top 2nd floor. That's 15 steps I've had to carefully carry her up after 2 surgeries for her ACLs. The last time she needed my help, I prayed up each step while leaning on the rail with my elbow for balance. Twice I feared we were going to fall backwards. Thankfully she figured out how to 3 leg it up if she must. I love her more than anything & will do all I can to help her, but I know she'll be my last pup. I would have curled around her had we fallen. Allergic to cats, birds, don't like fish. So every day we have together I treasure. When did we become like we are? I still remember picking up a sick, skinny, rescue pup of 4 months. She rescues me every day & all nite by staying close by. I'll do no less for her.🐕‍🦺💜
