Tracheal collapse is a common cause of airway obstruction in dogs. The trachea, or “windpipe,” is a tube made up of sturdy rings of cartilage through which air is transported to and from the lungs. Sometimes, however, the tracheal rings begin to collapse, and as air is squeezed through, a characteristic honking cough results.
Why tracheal collapse occurs is unknown, although a congenital abnormality, in which the cartilage of the tracheal rings is less cellular and therefore weaker than normal,...
But vomiting can also be a sign of a serious and even life-threatening illness in our pets. Here are facts you need to know about dogs' vomiting.
Vomit or Regurgitation?
There are two ways that dogs throw up.
When food stays in the esophagus because it is blocked or won’t go down, it accumulates until it is overloaded and the dog regurgitates the food. Although this process may appear similar to vomiting, it is actually called regurgitation. This food often appears tubular in shape and undigested because it has not actually made it to the stomach.
But when the food reaches the stomach, it has to be forcefully expelled through vomiting. Dogs that are about to vomit usually become anxious and may seek attention or reassurance and exhibit signs of excessive drooling and swallowing.
Why Dogs Vomit
Common causes of vomiting are eating indigestible substances, overeating or eating too fast, exercising immediately after eating, motion sickness, stress, and worms.
If a dog vomits only a frothy, clear or yellowish fluid, it probably has a stomach problem, such as acute gastritis, but it also could have pancreatitis, peritonitis, or an intestinal obstruction.
And going through the motions of vomiting, but not bringing up any vomitus could be a sign of bloat (also called gastric dilatation and volvulus, or GDV), a very dangerous and often fatal condition in which the stomach twists inside a dog.
When Is Vomiting a Serious Problem?
If an otherwise healthy dog throws up occasionally, it probably isn’t a problem. But if you see any of the following signs, take your dog to a veterinarian immediately:
Vomiting more than once per day, or continuing to vomit the following day
Vomit containing bright red blood or what looks like coffee grounds (this is partially digested blood)
Vomiting despite not eating for several hours
Vomiting also can be more dangerous in older dogs, dogs that already have health issues, and puppies. So keep a closer eye on those dogs and take them to your vet if they continue to throw up, because vomiting can severely dehydrate dogs.
