I kinda doubt the Ranger will be down on hands & knees - "reading tags"!
I don't think any of the rangers have even looked to see which dogs were mine or came even close to the dogs themselves. (Are they afraid of dogs?????) When they do come around they ask the adults if your dogs are registered and if you have your permit. In the past we have told them they were in the car (because it is true - they aren't that sturdy for us frequent users to keep on us) and they would just ask a question that you should only know the answer to if you had registered. Recently I was back at the car when the ranger came around and so I did have to get it out to show him. But again they seem to be more worried about their shot records than they are about licensing. Even to register you don't have to prove they have their license.

Amber, you get licenses from the county auditor's office which is usually in the court house. In Findlay you can also buy them at the Humane Society and at Pet Supplies Plus.

AngelZoo, I disagree with your number 8
8.) You really don't need to be there if you don't have a dog.
My dogs love attention from people and since I have five it helps me if others give them attention at the park. It has also helped with Snoopy who is afraid of people to have people just want to pet him. I think it has helped them all to relate and respond more appropriately to people (not bark, jump up, etc.)

I do think you have two that are extremely important
9.) Pay attention to your dog, and dogs around your dog.
and
11.) Watch out for everyone else and their animals, it's your best defense for your own safety.
Some people come to the dog park to let the dogs run while they
talk to other dog owners - or to get their walking exercise in - or to just sit and relax while their dogs do whatever they want.
