Our pups are just over a year old and they seem to be calming down earlier in the evening than usual. When they were younger they would be playing and romping around until 9 or 9:30 every night. But lately, they pass out around 7 or 7:30. Are they at the stage when they start being less active and start sleeping earlier? Or are they bored? Or tired? They never lay down and relax unless my husband and I are. So when we get home from work, we make dinner and do some nightly chores and they're always following us around and being near us so as soon as my husband and I sit down for the night, the pups fall instantly asleep. Any ideas?
