Your temps get alot warmer than here so I may not be the best one to answer. I take mine for short walks in 90's degree weather about every day. We walk to meet my Daughter and walk home from school. They are also out in our front yard but not for long periods of time. We tend to hang out in the backyard where we have a big walnut tree for shade. Now if I want to take them on a long walk we go in the evening or morning |
