Stop Snoring Remedies

I have a 6 year old doxie I adopted from a shelter. She was chubby when I got her, but seems to have gained more weight. In addition to the obvious back concern, she has started making a rather loud snoring sound, not only when she sleeps — all the time. It seems to have gotten worse as she’s gained weight.
Could her weight be causing this? And, also any suggestions of what the best food is to help a dog lose weight? I’ve been trying several different things — nothing works!

i heard my dad make a whistling noise while he was breathing at night, first it was normal, then around every 10 seconds i would hear a little whistle. i saw the lung cancer commercial about hearing a whistling noise. my dad smoked since he was 12 and now he is 40. he had a checkup for lung cancer in february and nothing was found. the whistling noise also wasnt very loud, it was kind of faint.
