If you chose to abandon your dog at the Dog Park you need to realize that they are not guaranteed a happy forever home or life! Abandoned dogs are reported to RB Animal Control. They make every effort to find out who the owner is through micro-chips because we know no one abandons a dog with a collar that identifies them!
If the owner cannot be found the dogs are taken to the Carson Shelter where IF they are lucky they find forever homes. MOST of them are not lucky. Are you willing to take that chance with your dog?
There are rescue groups that will help you re-home your dog. Give it a chance!
