Vet warns owners not to dress their pets up for Halloween
Veterinarian Dr. Kelly Hood explains the dog and cat stress signals owners can miss during costumes, family photos and trick-or-treat visits.
A dog that suddenly freezes in a Halloween costume may look perfectly posed for a photograph. But that stillness can be a sign of stress, rather than a willingness to cooperate.
Ahead of October 31, Dr. Kelly Hood, DVM, speaking for Pet Health Digest, is encouraging owners to watch what their pets are communicating before asking them to sit through another photo.
“The Halloween photo isn’t worth making your pet uncomfortable,” says Dr. Hood. “If your dog goes rigid, turns away or keeps trying to leave, put the camera down. You don’t need to wait for a growl or a snap to take those signals seriously.”
The ASPCA warns that costumes can cause unnecessary stress and advises dressing pets only when owners know they enjoy it. Outfits must not restrict movement, vision, breathing or the ability to bark or meow.
Read the pet, not just the picture
Discomfort can look different in dogs and cats. These signs should be considered alongside the animal’s whole body, normal behavior and what is happening around them. A single yawn or change in ear position does not establish that a pet is distressed.
| What to watch | In dogs | In cats |
| Face and ears | Repeated lip licking without food, yawning when not tired, turning the head away or pulling the ears back. | Ears rotating sideways or flattening back, especially alongside a tense posture. |
| Body posture | Suddenly freezing, becoming rigid, crouching or tucking the tail. | Crouching low, flattening against the floor or holding the tail tightly against the body. |
| Attempts to avoid the situation | Backing away, hiding or avoiding touch. | Leaning away, retreating or hiding. |
| Escalating warnings | Growling, baring teeth or snapping. | Hissing, growling or swatting. |
These behaviors can signal fear, stress or a need for space. Owners should respond before discomfort escalates.
“A cat crouching in a costume with its ears flattened isn’t necessarily being patient,” says Dr. Hood. “And purring alone doesn’t always indicate a cat is happy. Look at the whole animal, including whether they are relaxed and able to move away.”
When to stop the photo
If a pet becomes tense, freezes, repeatedly avoids the interaction or tries to escape, end the photo session. Remove the costume calmly if it is safe to do so, reduce the noise and attention, and give the animal space.
Do not hold a pet in position, chase it for another shot or bring it back after it has walked away. Never punish growling: it is a warning that the dog needs space, and suppressing it can make future reactions harder to anticipate.
Breathing difficulty is a medical concern, not something to dismiss as Halloween nerves. Seek emergency veterinary help if a pet is struggling to breathe, including a cat breathing with its mouth open.
Make a plan before the doorbell starts
Halloween can bring repeated doorbell rings, unfamiliar voices and visitors whose costumes change their appearance. The ASPCA recommends a separate, comfortable room away from the front door for all but the most social pets during busy trick-or-treating hours.
Prepare that space before visitors arrive, with familiar bedding, water and somewhere to hide. Cats should also have access to a litter box. Ask guests and children to leave resting or hiding pets alone.
“A pet that usually welcomes visitors may find a stream of masked strangers overwhelming,” says Dr. Hood. “They don’t have to greet every child at the door to be part of the family’s Halloween.”
Keep the Halloween theme off the pet
A costume-free photograph can still capture the occasion. Owners can wear the costumes themselves or add a Halloween border to the finished image.
If a pet already enjoys wearing an outfit, check its fit beforehand, avoid loose pieces that could be swallowed and stop if its behavior changes.
“Let your pet choose whether to approach and stay,” says Dr. Hood.
“If getting the picture means preventing them from leaving, that is your cue to stop.”
