Most definitely. I use to work as a dog groomer and a regular client of mine brought her dog in for a both but was concerned about her dog because he had started limping a couple days prior. I looked the dog over and found nothing that I could see wrong. I assured her that I would accommodate her dog as needed. As soon as she left, the dog stopped limping. I called her to let her know and at pick up, I showed her that her dog was faking it by having her hide. No limp. But as soon as the dog saw her, he started limping again. It was the funniest thing.
