This is my first summer with Whiskey and I was just wondering, if anybody has seen this behavior with their pups. Whiskey's a little active in the morning but as the day goes on, he prefers to snooze or just lie down. He is quite energetic on his walks in the evening when I take him out at around 6:30 pm. He is the most active after his walk and until his bedtime. Is it just his way of tolerating the heat? I have heard that quite a few dogs slow down in the summer?
