I ADORE my dog (3-year-old GSD). However, this evening I just needed space from him and his separation anxiety (working on this with behaviourist). After having a long walk, food and water I left him in our spacious kitchen. I just needed to be on my own in the bath. He is perfectly fine but he is whining as if he is being murdered right niw. Am I terrible for leaving him? I really love him but just need a minute away from him. Feeling guilty.
