Aww poor baby left outside. Why do people get a dog and then banish them outside to be alone. ? If you're not willing to treat them like part of the family why have a pet? Anyways that's my vent. Thank goodness for you, he's lucky to have you. It's only been 2 days, and he probably is just transitioning, and getting used to his new home and surroundings. He's been left outside in the past, so that's what he's used to, and now he's inside and in a comfy bed, and it's all new to him. Give him time to adjust and to trust you , and he will settle in before you know it. With love and patience he will grow to love you back, and he will start to learn his new routine. Good luck and I'm glad Oliver found you.
