stuck puppy and derby hiccup

I have a strange bug: one of my puppies has been sat in the same spot for two days. Nothing I've tried will move it, it sleeps here, eats here, and will not return to its bed no matter how often I whistle.
This morning a derby task I was working on, happy town visitors, failed to count up as I served them. Really frustrating as half a dozen people happy stood with gifts and none was counted off my total. Are these two glitches related?

Have you tried rebooting the game? Just switching the game or your device completely off and then switching it back on? Then put your pet bed in an open space and use the whistle again. Sometimes a reboot solves several problems. The task one sounds weird and if a reboot doesn't fix it you ought to contact the in-game support team through your game settings (in my opinion).
