Which shelter? Chances are you signed a contract saying you’d return the dog to them. Do you have an email address for anyone there? Most shelters right now are working on skeleton crews. How long has it been since you left a message? Also, just as a side note, don’t let anyone tell you it’s ok to go against the contract. If you breach it there could be consequences. Only wanted to say that bc of some of the comments made. I worked at a Humane Society for many years. It’s not ok to rehome an animal on your own if you’ve signed something saying you’ll return it. I’m not saying you would. just wanted to throw it out there since others are suggesting.
