For the last three days ( 18, 19 20 th ) it has been hotter than hell on Ceeo Alto , yesterday at 6 PM it was 92 degrees at the trail.head . I spent more time letting Sierra play in the water than I did hiking . She loves the water , the heat not so much . We started up the canyon trail at 6 pm and took our time reaching the four way intersection ( 1.7 miles ) one hour passed and the temp dropped 10 degrees making the balance of the hike bearable for Sierra . Remember that dogs can't take the heat like humans can . At this hour the shadows are long and Sierra was in the shade most of the time . Remember that Sierra and I hike seven days a week so she is in good shape . If you are new at hiking with a dog , please read the suggestions I have posted on the subject listed on the right column under " Labels " , ( hiking with dogs ) there you will find advice on water needs for warmer temperatures , over heating symptoms for dogs and proper care .
