I'm a little worried! My little girl started this huffing and puffing this morning about 4 am ( I woke up feeling sick, and so she woke up too). She has just started this huffing and puffing, I've had her since last July and she has NEVER done this. She sleeps with me and my husband on our king size bed, so plenty of room for her. She has only done it when she is laying down and it only goes on for 15secs at the most, then she stops ( for awhile sometimes) and then it starts again. Sometimes she is a sleep and sometimes she is awake when she does it. During the day today she didn't do it at all! Then she came to bed with me and she started it again. The only change has been not going to the dog park as often due to weather. I just washed the sheets and comforter yesterday, but I used the same stuff I always have. Is it a sign of something wrong? Her nose is a little dry, but I know they do that sometimes when they sleep. Any help would be greatly appreciated!!
