Puppy Breathing Fast In Sleep. Small dogs often breathe faster than larger dog even when relaxed. Should you call the vet?
Rapid puppy breathing and sleeping. Your puppy should stop breathing fast as soon as they move on from that dream or that particular rem cycle while sleeping. Sleeping is very important to puppies as it’s during sleep that their growth and development take place.
The answer is that it depends.
Your puppy might also experience rapid breathing (also known as tachypnea) if they are scared or nervous, such as in a new environment, meeting new dogs, or if they are going on a car ride — these are times of heightened awareness and anticipation. He is also very restless when sleeping. I just bought a puppy and he is breathing very rapidly even when laying down and sleeping. She stops breathing fast if i wake her up but i'm still worried.
