How it works
Fill out the entry form with up to 3 costume photos (JPG, PNG, WebP or HEIC) and a short description of the look.
One vote for Team Dog and one vote for Team Cat per email address. Confirm each vote with the link we email you before voting closes Oct 30, at 12:00 AM CDT — votes confirmed after the deadline are not counted.
The Dog and Cat entries with the most eligible votes win their category.

Halloween pet safety · From your emergency vet
Halloween is one of the busiest nights of the year for pet emergencies. A few simple swaps keep the scares on screen.
Chocolate is toxic to dogs and cats — dark and baking chocolate are the most dangerous. Keep the candy bowl well out of reach.
Many contain xylitol, which can cause a dangerous drop in blood sugar and liver damage in dogs — even in small amounts.
Raisins and grapes can cause sudden kidney injury in dogs. Watch out for trail mix, cookies and party snacks.
Foil, wrappers and sticks can cause choking or a blockage in the gut. Bin them straight away.
Glow-stick liquid irritates mouths and makes pets drool; candles and jack-o’-lanterns can singe curious noses and tails.
Choose costumes that never restrict breathing or movement, and give anxious pets a quiet room away from trick-or-treaters.
If your pet ate something they shouldn’t or just isn’t acting right, call us right away — don’t wait for symptoms.
General guidance, not a diagnosis. If you’re worried about your pet, call your vet or an emergency hospital right away.
The not-so-scary details
You may cast one vote in each category (Dog and Cat) per email address. Tap Vote on any entry, enter your email address and we will send you a confirmation link. Your vote counts once you click it. Public voting runs Oct 27 – Oct 30.
You get one vote in each category: one for your favorite in Team Dog and one for your favorite in Team Cat. A second vote in the same category from the same email address will not be counted.
Email confirmation keeps the contest fair by stopping automated and duplicate votes. Votes that are never confirmed are not counted. Voting closes October 30, 2026, at 12:00 AM CDT: a vote confirmed after that moment is not counted, even if you cast it earlier, so click the link as soon as it arrives. Not seeing the email? Check your spam or promotions folder.
To keep the competition fair, voting activity is monitored. Only confirmed, eligible votes count toward the results — votes that appear to be duplicated, automated or otherwise fraudulent may be excluded.
You can upload up to 3 photos per entry in JPG, PNG, WebP or HEIC format, up to 8 MB each. HEIC photos straight from your iPhone are welcome too.
Anyone! There is no ZIP code or location restriction for this contest. Choose the Dog or Cat category when you enter. Every entry is reviewed before it appears in the gallery.
Winners will be announced on October 31, 2026. The Dog and Cat entries with the most eligible votes win their category.
Each winner takes home a Halloween gift basket: a $100 gift card, an Allied Angel Fund blanket, an Allied bandana and toys and treats. There may be a few extra surprises tucked in, too!
Prizes are picked up at any Allied Veterinary Services location. Please pick up your prize by November 30, 2026, at 6:00 PM CST. Prize pickup is in person only, and prizes cannot be mailed. Choose the location that suits you and our team will coordinate getting your prize package there.
