As the sky darkens unexpectedly, dogs may become confused or unsettled, mistaking the sudden change in light for an early sunset. Darren Beale, CEO of fresh dog food brand Years, said: "Dogs will not understand that an eclipse is taking place. Owners should also provide a quiet, familiar space and avoid taking anxious dogs to busy eclipse-viewing locations. Eclipse glasses are not necessary for dogs, as they are unlikely to look directly at the sun. He said: "Trying to put eclipse glasses on a dog could cause more stress than the eclipse itself."
