A question about older dogs.

My Labrador will be nine next week. She has hip dysplasia, but manages pretty well with pain medication. She still loves to go on long walks – and being a typical Labrador, rain has never deterred her in any way. My problem is: Whenever she gets wet, her hip gets worse. One two-hour walk in the rain, and she is very obviously in pain for at least until the following morning. She has trouble getting up, sitting, even standing for too long. I hate when that happens, it kills me to see her in that state. Which brings me to my question: Would you skip the walks? I’m torn about this. I would miss them myself, because I like walking in the rain. And she loves it. But of course, she doesn’t realize she will be in pain afterwards… What would you do?
