Thanks for ALL the advice! I had never heard of megaesophagus before! I checked in out on the Internet and found a great medical site. I will definitely keep my eye on her with this in mind. She is NOT making the noise anymore.
She is in perfect health otherwise. You know how pups sigh /breathe fast/noisily when you cuddle them. Just twice in the same day she made this funny noise along with that. Sorry to alarm you all. I just thought someone here might have also heard /seen this before.
Just a foot note, I am NO FOOL
and really care for/ look after ALL my dogs
,(cats as well) and I know when it's time to take them to the vet and of course I will take her if it returns. They will all be going at 6 weeks. I will definitly ask him about this. Thanks all the same.
