Breathe Right strips for dog?

[schlepsnort]

The last few nights our cocker spaniel has been snoring very LOUDLY. The first night I kept kicking DH thinking it was him but then I paid more attention to where the sound was coming from and realized, it was the dog. The worst night was when DH, the spaniel, the St.Bernard AND the boxer all started snoring at the same time.
I have never heard a dog snore this loud. Now I say her name and she stops for awhile but it is window shaking loud when she really gets going.
Anyone else have pets that do this?? Is it just because they are THAT deeply asleep or narrow nasal passages?
It is just so weird.
