I thought I would never write this about my dog. She used to live for a run on a local field with her ball, you couldn't throw it enough for her, but the last two times she hasn't wanted to play and has walked off after one throw.
She is 5, has some arthritis in one joint but that's under control with medication, and it has never stopped her before.
I'm just baffled why she has suddenly lost all interest. She wants to go to the field and pulls to get there, so it's not an experience on the field that has put her off.
Any ideas?
