How do I choose the right size alligator costume for my dog?

Measure your dog's chest at the widest part and their length from the base of the neck to the base of the tail, then compare these measurements to the manufacturer's size chart.

Can I walk my dog while they are wearing this costume?

Yes, look for costumes that feature a built-in leash portal or harness hole on the back for safe walking.

What should I do if my dog hates the hood?

Simply fold the hood back off their head and let it rest on their shoulders; they will still look like an alligator from the neck down.
