Dog bloat is a serious condition that can be fatal.  Dog bloat is also known as Torsion or Gastric Dilatation-Volvulus (GDV). 

In general bloat is a problem for larger dogs. But since dachshunds have a large chest cavity, they’re at risk too. Some people suspect that dogs' genetics can predispose them to this condition. No matter what, if your dog is showing any symptoms dog bloat, consult a veterinarian immediately. 

When dog bloat occurs, it’s because the dog's stomach fills with distended gas or air, then the stomach twists. As a result of the twisting, the dog can’t vomit or burp to get rid of the excess air. Then blood can’t get back to his heart properly

In this situation the dog’s blood pressure will drop dangerously low, and he may go into shock.

Again, if this happens to your dachshund, you need to immediately take him to the vet or even better an animal hospital. That way they can determine if it's dog bloat or another medical condition. 

It’s a medical emergency and your dog could die if he’s not treated properly and quickly. 

Symptoms of Dog Bloat

There are some ways to see that your dachshund may be developing bloat. For example:

• If your dog’s abdomen is swollen and distended.
• If he seems lethargic, depressed, or weak.
• If his heart rate is weak.
• If your dog is salivating a lot or dry heaving (retching) but no food is coming out.

Be Preventative

One thing you can do to help prevent dog bloat from happening is make your dog slow down when she eats food.

We do this with our spaniel by flipping over her food dish (Cocoa, our dachshund, is a slow eater so it's unnecessary). That way the food goes inside the inner ring formed by the rim of the dish.

It's made a huge difference and I think she actually enjoys the challenge of getting her food out of it.

You can also buy special food dishes designed specifically for this purpose. But again, ask your vet what's the best strategy.
