The difference between a dog who trots happily down the street in a pumpkin suit and a dog who freezes on the porch is almost never the costume. It's the week before. Here's how to use it.
1. Start with the costume on the floor
Leave it where your dog can sniff it for a day. Drop a couple of treats on it. You want the costume to be boring, not scary.
2. Two minutes, then off
Put it on, give a treat, take a short walk around the room, take it off. Do this once or twice a day. Stop before your dog gets frustrated, not after. By day three or four most dogs stop noticing it.
3. Build up to a real walk
Once your dog is relaxed indoors, do a short outdoor walk in the costume. Outdoor smells are a great distraction, and it lets you check that nothing shifts, rides up or drags when the dog actually moves.
4. Know the signs to stop
Freezing in place, repeated head shaking, pawing at the face or a tucked tail all mean "not yet". Take it off, give it a day, and try a shorter session. A dog that's stressed on Halloween night is no fun for anyone, and no photo is worth it.
5. Pick the right style for your dog
Dogs that hate having anything on their heads do well with capes and harness-style costumes: the vampire cape, bat wings or the bat-collar cape for big dogs. Dogs who already wear coats or sweaters happily can handle full-body costumes like the pumpkin or dinosaur.
On the night
Put the costume on right before you head out, not an hour early. Bring treats. Take it off for water and when you get home. And take the photo early, while everyone is still fresh.
