Lhasa Apso Q&A
Any dog can adapt to being alone at home. The crate or kennel can greatly help in this. Make sure you are properly training them for the kennel and not just throwing them in there and walking out.
No dog should be left alone all day, every day. Very few people could stand it so why should we expect our dogs to? If you work full time do not get a dog. I have two dogs and have never left them alone for more than 4-5 hours except when it really couldn't be avoided.
