Dogs are not allowed in Petco stores, except for service animals.
This policy is in place for the safety of both dogs and store employees. Dogs can be unpredictable, and even the friendliest dog may bite if it feels scared or threatened. Store employees may not be comfortable around dogs, or may be allergic to them.
Service animals are an exception to this policy, as they are trained to behave around people and other animals. If you have a service animal, you should let a store employee know so that they can accommodate you.
