If your dog’s pupils are always dilated—no matter the time of day or lighting—it’s completely understandable to feel concerned, and veterinary input is definitely warranted. Just like ours, their pupils should adjust to light, dilating in the dark and constricting in brightness. It’s also imperative to seek prompt veterinary care if you notice their pupils are uneven, seem to quiver, or stay dilated alongside signs like bumping into things or walking in an unusual way. These changes could point to something serious, and getting help early can make a big difference.
