IS there anything you can give your dog to euthanize her at home?

No, and please do not try to do this unless you are a medical professional and have legal access to veterinary medications. Anything you might try to give your dog to induce death could result in a terrifying, painful, lingering experience for your best friend. Shooting a pet or slitting its throat could result in the same consequences. The only humane way to euthanize a dog is to take it to a veterinarian, who can administer the proper chemicals to kill the animal without causing fear or pain. These chemicals will first cause the dog to lose consciousness, then stop the beating of its heart. If money is an issue, contact your local humane society. Many such organizations offer free or low-cost euthanization.
