The best first aid is to pop some Gas-X or activated charcoal into the dog, and GET TO THE VET. If you are unsure if this is bloat, then off to the asap vet. Time is of the essence to save damage to the organs and for the actual survival of your dog.

For the Gas-X, if you have gelcaps, puncture them first, then squirt the contents in the back of the throat and try to get them to swallow the pill. There are liquid forms, and also strips that melt in the mouth. Always good to keep extra in your purse, car, etc.

What Are Signs and Symptoms? Remember, not all of these can or will happen at the same time—these are things to be looking for:
• Abdominal distention (swollen belly) makes it obvious—this does not always happen, or happen right away
• Nonproductive vomiting (animal appears to be vomiting, but nothing comes up) and retching. Sometimes white foamy liquid or mucous will come out.
• This seems to be one of the most common symptoms & has been referred to as the
"hallmark symptom"
• Some reports say that it can sound like a repeated cough
• Restlessness and/or anxiety, whining
• Not acting like themselves
• Asking to go outside in the middle of the night. If this is combined with frequent attempts to vomit,and if your dog doesn't typically ask to go outside in the middle of the night, bloat is a very real possibility.
• Abdominal pain and/or discomfort
• "Hunched up" or "roached up" appearance (also a sign of pancreatitis—another medical emergency)
• Lack of normal gurgling and digestive sounds in the stomach. Many dog owners report this after putting their ear to their dog's stomach If your dog shows any bloat symptoms, you may want to try this immediately
• Pale or off-color gums: Dark red in early stages, white or blue in later stages
• Rapid shallow breathing and/or panting
• A lot of drooling may indicate severe pain
• Digging bedding
• Licking bedding
• Unable to get comfortable
• Drum like thumping noise when you hit their sides
• Coughing
• Foamy mucous around the lips, or vomiting foamy mucous
• Pacing
• Unproductive attempts to defecate
• Licking the air
• Seeking a hiding place
• Looking at their side or other evidence of abdominal pain or discomfort
• May refuse to lie down or even sit down
• May stand spread-legged
• May curl up in a ball or go into a praying or crouched position
• May attempt to eat small stones and twigs
• Drinking excessively
• Heavy or rapid panting
• Shallow breathing
• Cold mouth membranes
• Apparent weakness; unable to stand or has a spread-legged stance especially in advanced stage
• Accelerated heartbeat: heart rate increases as bloating progresses
• Weak pulse
• Collapse

Pneumonyssoides caninum infection--a risk factor for gastric dilatation-volvulus in dogs.
Bredal WP.
Vet Res Commun. 1998 Jun;22(4):225-31
Department of Small Animal Clinical Sciences, Norwegian College of Veterinary Medicine, Oslo, Norway.

The pathophysiology, clinical course and therapeutic management of gastric dilatation-volvulus (GDV) in dogs are well known. However, the aetiology remains elusive. Aerophagia has often been put forward as a contributing cause of GDV. The most common clinical sign in dogs with nasal mite (Pneumonyssoides caninum) infection is 'reversed sneezing', which may result in aerophagia. A prospective one-year necropsy study was conducted. Of 250 dogs, 17 were GDV cases and, of these, 35% had concurrent nasal mite infection compared to 5% in the control population. Multivariate logistic regression analyses performed using the 187 dogs with complete records included nasal mite infection status, age, weight and gender. Nasal mite infection was found to be the most important risk factor for GDV in this study, with an odds ratio and confidence interval of 27.6 (4.8-157.5). Other risk factors that were marginally significant included weight and age with odds ratios of 1.08 (1.02-1.13) and 1.37 (1.04-1.79), respectively. Gender was not found to be a significant risk factor for GDV. This study suggests that nasal mite infection may contribute to the development of GDV in otherwise predisposed dogs.

Meteorological influence on the occurrence of gastric dilatation-volvulus in military working dogs in Texas.

Gastric dilatation-volvulus (GDV) is a life-threatening condition in dogs and other species in which the stomach dilates and rotates on itself. The etiology of the disease is multi-factorial, but explicit precipitating causes are unknown. This study sought to determine if there was a significant association between changes in hourly-measured temperature and/or atmospheric pressure and the occurrence of GDV in the population of high-risk working dogs in Texas. The odds of a day being a GDV day, given certain temperature and atmospheric pressure conditions for that day or the day before, was estimated using logistic regression models. There were 57 days in which GDV(s) occurred, representing 2.60% of the days in the 6-year study period. The months of November, December, and January collectively accounted for almost half (47%) of all cases. Disease risk was negatively associated with daily maximum temperature. An increased risk of GDV was weakly associated with the occurrence of large hourly drops in temperature that day and of higher minimum barometric pressure that day and the day before GDV occurrence, but extreme changes were not predictive of the disease.

Dietary potassium-sodium imbalance as a factor in the aetiology of primary ruminal tympany in dairy cows.
Vet Res Commun. 1981 Dec;5(2):159-64.
Turner MA.

Results of an investigation into the chemical composition of pasture herbage on twelve New Zealand dairy farms, with contrasting incidences of primary ruminal tympany (bloat), are presented. The data suggest that dietary K;Na ratio may be an important factor in the aetiology of bloat; a factor that does not seem to have been recognised in the past. Other supportive evidence for this hypothesis is briefly discussed.

Nutrition: Is it a Factor in Bloat and Torsion? by Linda Arndt
Torsion: Could it be an Electrical Short-circuit?

Gastric myoelectric and motor activity in dogs with gastric dilatation-volvulus

Electrical and contractile properties of the stomach were assessed in six adult dogs after recovery from surgical treatment for gastric dilatation-volvulus (GDV), a disorder characterized by delayed gastric emptying of the solid phase. Electrodes and strain-gauge force transducers were sutured to the serosa of the antrum and pylorus at the time of surgical intervention for GDV. Ten days after implantation, electrical and mechanical activities were recorded before and after a standardized meal. The analog FM tape recordings of the electrical and mechanical signals were converted to digital time series for analysis by computer. Recordings from dogs after GDV showed increased slow wave propagation velocity in both the fasting and the fed states compared with controls. In addition, the GDV dogs had atypical fasting state phase III activity fronts. We found no difference in gastric slow wave frequency, dysrhythmia, or electromechanical coupling between the two groups. These results indicate that delayed gastric emptying in this syndrome is associated with increased gastric slow wave propagation velocity.
