Hiking is meant to be an adventure, and in the hot summer months, this could turn out to be more of an adventure than what one had planned for. Especially when you have K9s in your group.
During the summer months it is much better to do short walks with your K9s, either early in the morning, or late afternoon.
Dark coloured dogs are more at risk due to the fact that they absorb heat faster.

Be out and be safe.
