My dog does the same thing and after he was x-rayed for inspiration pneumonia, it was discovered that he is suffering from a condition called mega esophagus. The esophagus is enlarged and food doesn't go all the way down into his stomach. This causes him to regurgitate whatever is in his stomach at the time. Ask your vet about this condition. I hope this helps.
I have found that several small meals a day given from an elevated bowl and elevating his head when he sleeps helps quite a bit.
My dog, who is about 11 years old, did the same thing. It
happened when he started to eat; he would gag, cough, want to run
outside and eat grass and then spit up. The vet told us his gums
and teeth were sore and to feed him soft food or put water on his hard
food. We did, and guess what? No more gagging, coughing,
eating grass or spitting up. In fact, if I don't put water on his
hard food now, he just stands and looks at it, then at me and then
growls until I put the water on it. Go figure...
Sounds like the veterinarians you have seen have done a very
thorough workup. Common things happen
commonly—and general practitioners are good at diagnosing and treating common
things. The specialists at Auburn are the experts at
the uncommon—which your beagle falls into.
My two cents are—watching her lick and lick in the video
seems to be a compulsive behavior. Can
you link the behavior to a time of day, event that has happened, any changes or
stresses in the environment? If you can
find the source that triggers the OCD behavior it will help treat the problem. A veterinary behaviorist or in house trainer
may help identify the problem.
Another possibility is that the smacking of the lips is a
sign of nausea. Have you tried placing
the Beagle on Pepcid to reduce nausea? The
dose is 0.5mg (milligram) per kilogram of body weight and can be given orally
Lastly is there anything you clean with or put on the carpet
or floor that the Beagle likes the taste of? This could lead to the licking and then nausea
from ingested carpet fibers or dirt.

You dog has kennel cough its similar to our bronchitis. Take your dog to a vet they will give you antibiotics. My dog just had it so I'm positive that's what your puppy has.
