If your pet stays outside for any length of time, remember to provide a source of cool water in a bowl that won’t get hot.  Provide shade.  A covered patio, with something other than hot cememt on which to lie, can do the trick.  So can a screened-in patio.  On really hot days, consider letting your pet stay inside your house, especially if it’s cooler than outside.  Never keep a pet in a garage unless it’s air-conditioned.  Garages can get too hot for animals to remain comfortable if stuck inside.
