Grace is 11 years old. She is a very submissive, sweet dog that has recently developed some severe separation anxiety. We have tried numerous things, and medications and she cannot be left alone, or will pee and poop in the house. She has been houstrained for a decade. She has always been a nervous dog. She lays in her bed and whines or shakes for no reason. She has never been a dog who plays. she just needs loves. She is agoraphobic, and doesn't like to go on walks, as she is very nervous. She will run around the backyard with us, though.
