Hello, my name is***** and I have over 20 years of experience as a veterinarian. I'd like to help with your concerns about Buster vomiting clear mucous and groaning in discomfort every time he moves.
Vomiting/retching in dogs can be from several causes. Common ones are a quick change in diet, too many treats, especially fatty or spicy treats, eatings things they should not such as things found in the yard, toy pieces or garbage, viral or bacterial or parasitic infections. 
More serious causes include pancreatitis, esophageal reflux, a dietary allergy or sensitivity, inflammatory bowel disease, internal organ failure (kidney or liver disease), a full or partial gastrointestinal obstruction, a twisted bowel, or even infiltrative cancers such as lymphoma.
But his symptoms signify severe abdominal pain. We can see those sorts of symptoms with severe pancreatitis, an obstruction, a twisted bowel or peritonitis due to a leaky or ruptured bowel.
I recommend that Buster be seen on an emergency basis as soon as possible. A thorough examination, blood tests, radiographs and possibly an abdominal ultrasound may help determine his source of pain.
If there is no way to have him examined today there are some things that we can try, but this is not ideal.
To try and settle his stomach now you can try either:
1) Pepcid-ac (famotidine) at a dose of one 10mg tablet per 10 to 20 kilograms of body weight 
every 12 hours.
OR
2) Prilosec (omeprazole) at a dose of one 10mg tablet per 10 to 20 kilograms of body weight 
every 24 hours.
These will reduce stomach acid and should help if this is related to simple nausea and gastrointestinal irritation from eating something he should not have.
I would not feed him any food for 24 hours even after the acid reducers are started.
 This should help stop gut spasms and restore normal gut motility.
Starting a couple hours after the acid reducers small amounts of water or ice cubes given frequently are fine as he needs fluids after all that he has lost with vomiting.
You can give him pedialyte to replace electrolytes too but Gatorade is much too high in sugar which can make his gastrointestinal irritation worse.
If things are going well after his food fast and the acid reducers start a bland diet of 1/3 boiled, lean hamburger (or boiled, white, skinless chicken), all fats and juices drained off the meat, mixed with 2/3 boiled, plain white rice or pasta. Feed several small meals a day.
Once he feels better (no vomiting for 48 to 72 hours) start mixing in his regular dog food very slowly. Less bland more regular with each day. It should take a week or so to convert him back.
If Buster is continuing to vomit and is feeling poorly though, especially if he remains so uncomfortable, it would be best that he see a veterinarian now as anything you give him orally will just come back up worsening his dehydration.
Because he has a tense painful abdomen, is very lethargic, and is vomiting, especially if he runs a fever greater than 103.5F (39.7C) then he really should be seen by a veterinarian as soon as possible.
Best of luck with your little one, please let me know should you have any further questions.
