Alternatively, you can try getting a white noise machine which does a good job of drowning out the noise at night. Lastly, if your dog is crate trained, putting a thick blanket over their crate seems to minimize noise.
Vivid dog dreams will occur the most in a sleep phase called Rapid Eye Movement (REM). In the REM sleep phase, the dog’s brain is most active and many experts say that dogs dream at least 4-6 times per night.
It’s also well known that smaller dogs tend to dream more often and bark in their sleep as compared to larger dogs. This is the same effect as in humans as babies can spent 50% of their sleep in a REM cycle.
