Daisy rides in the van (all over it--whichever rear seat she chooses) by her air vent. The back windows only open a little, so her nose may be sticking out somewhat.And I make sure the child locks are on, so someone doesn't accidentally open the slide door.(she likes to bolt) I see plenty of poor pooches locked in hot cars while their owners are shopping... would'nt ya just like to slap them??
