Puppies do breathe faster when they are in REM sleep, but since he has a murmur it would not hurt to at least talk with a specialist and have his grade taken again. At 8 weeks it is not uncommon for a pup to still have a murmur as a grade 1-2, sometimes the valve hasn't closed yet in growth. At 13 weeks it's possible it won't. But a grade 2 murmur should be okay-- may downgrade to a grade 1 with growth. I'm a bit surprised the breeder did not mention it to you? Murmurs do not develop they are born with them.
