Sign of pregnancy: deep rhythmic breathing - Page 1

My girl was bred Oct 8 and 10.

She is having deep abdominal movement with breathing that I have never seen in her before.  Her appetite has also been unusually good. 

Are these signs of pregnancy?

Thanks

i have found most pregnant dogs loose alittle appetite around third week into pregnancy skipping meals. i do not know about the breathing could be she just feels good not Halo
