Question: are dogs ok on their own?
Answer: Big Dogs. Larger dogs can be on their own, too, but they need more space to feel comfortable. ... Breeds of big dogs that can be left alone include Shar-Pei, Greyhound, Bullmastiff, or Labradoodle. It's important to stress that, even though some dogs cope better with being alone, it doesn't mean they should be neglected.
