Is Respiratory Rate Higher In The Morning Or Night Heart/respiratory Rate For A Puppy?

Heart/respiratory rate for a puppy? - is respiratory rate higher in the morning or night

I have a Golden Retriever, 11 weeks, and I noticed that appears when you sleep your heart / respiratory rate is quite high - much like a man after running laps. I have no idea what the regular prices seem quite high but for a puppy. Now, his respiratory rate 54/min and heart rate is too fast for me to have the hearing. What are the normal rates? When high, this can mean something serious?
