That's a great question! Unfortunately we can not allow dog to visit the sanctuary. We hope that will not dissuade you from visiting us.
The birds would be frightened of a dog walking around so dogs are prohibited. With the heat in Florida, it is unwise to leave your dog in your car. However, parking is a series of pull-offs off the Rehab Center's driveway. If one of you is willing to stay behind and walk your dog down the driveway to the road and back (away from the bird sanctuary, you could then switch places. Admission is a request for a donation, not by the individual so it would not cost more to do it. The Center is very nice but on the small side so it wouldn't be too burdensome to have someone with the dog and then switch places.
