I have a Shih Tzu that is about 10 years old, and he is having problems with his back hind leg. It is almost like there is a catch in his back. He is unable to jump and appears to be in some pain.
I recently saw an episode that said dogs need about a 45 minute walk per day. Well, I started walking my miniature dachshund this week, but we have only walked about 20 minutes each day so far.
