What are the chances of surviving drowning?
The case-control study described above reported a mortality rate of 74 percent, with 4 percent of victims surviving with severe neurologic disability. Of those patients who survive to hospital discharge neurologically intact, long-term survival appears to be similar to the general population [97,98].

Or rapid accumulation of fluid in the lungs may occur, causing acute respiratory distress. If the alveoli become filled with fluid instead of air, your dog will have reduced breathing capabilities due to low oxygen intake and limited carbon monoxide output.
Can a dog get water in their lungs from swimming?
Quite simply put, inhaling water while swimming causes excess fluid to build up in the lungs, making breathing hard. This can “drown” your dog hours or even days after swimming. Your pup will, essentially, seem like a drunk human if dry drowning does begin to occur.

Physicians believe that brain damage begins to occur after about five minutes of oxygen deprivation. “If you can rescue a child before that and restore their breathing with CPR, and get their breathing back, usually the children will recover,” Dr. Goodman says. “After five minutes, there will be brain damage.

Once submerged, the body stays underwater until the bacteria in the gut and chest cavity produce enough gas—methane, hydrogen sulfide, and carbon dioxide—to float it to the surface like a balloon.
Why do corpses bloat?
At the second stage of decomposition, the bloated stage, is when putrefaction begins. Gases that accumulate in the abdomen, therefore causing it to swell, give the body a bloated appearance.
