Frogs and Frog spawn

Haven't seen any frogspawn yet but............yesterday, whilst raking up some dead grass I "raked" up a huge dead frog. At least it looked dead but apparently they can play dead if threatened? I covered it with grass to hide it from the dogs but forgot to look for it today. It was very near the "dog bed" pond where there was spawn last year. I hope I didn't harm it.
