Hi everyone, My puppy is nearly five months old and just went for his first day of daycare. He cried and barked a bit when I left him, but the carer said he adapted very quickly and made firm friends with one of the other dogs. The place was recommended and reputable. However, once home my puppy started whining and sniffing everywhere like crazy. It's been four hours and he hasn't slept, even though he's wrecked. I've taken him to the garden, fed him, done some training, but still no sleep. He's watching me like a hawk and races after me if I leave the room to go to the toilet (I know this is pretty normal for puppies, but he stopped doing it recently). Is this standard behaviour after a first day at day care? Does he feel anxious and insecure because we were apart for a day?
