Exercise-induced collapse (EIC) is an inherited genetic neuromuscular disorder, primarily affecting sporting breeds like Labradors, causing sudden muscle weakness, wobbliness, and collapse after 5–20 minutes of intense, exciting exercise. Affected dogs remain mentally alert but, despite being fit, suffer temporary, sometimes fatal, collapses.

How do you treat EIC in dogs?

The best treatment in most dogs affected with EIC is avoiding the activities that are most likely to trigger an event. If affected dogs are removed from participation in these activities and not exercised excessively, the condition does not progress and these dogs can live normal lives as pets.

What are the symptoms of EIC in dogs?

Exercise-induced collapse can cause a variety of symptoms in affected dogs, which include the following:

• Wide stance.
• Muscle weakness, especially in the hind legs.
• Dragging hind legs.
• Lack of coordination, stumbling.
• Sudden collapse during exercise.
• Inability to move after exercise.
• Increased heart rate.
• Rapid breathing.

What dog breeds are prone to EIC?

The EIC mutation is common in populations of the susceptible breeds. In the populations of dogs tested: 5-15 per cent of Labrador retrievers have been affected, and 35-40 per cent have been carriers. 2-3 per cent of Chesapeake Bay retrievers have been affected, and 15-20 per cent have been carriers.

What does EIC look like in dogs?

Affected dogs tolerate mild to moderate activity but will display signs of EIC after 5-20 minutes of strenuous exercise. The severity of EIC varies, some affected dogs continue to run while dragging their hind legs while others have progression of weakness from rear to forelimbs resulting in a total inability to move.

U of M researchers discover gene causing collapse in dogs

What are the four stages of collapsed trachea in dogs?

The 4 stages (or grades) of collapsed trachea in dogs describe the severity, from Grade 1 (mild) to Grade 4 (severe), based on how much the windpipe's internal space (lumen) narrows: Grade 1 has a 25% narrowing with normal cartilage, Grade 2 has a 50% narrowing with partially flattened cartilage, Grade 3 involves a 75% narrowing with nearly flat cartilage, and Grade 4 shows total collapse (up to 100%) with completely flat cartilage, often causing severe respiratory distress.
 

What causes eosinophilic inflammation in dogs?

Dogs are most commonly identified with eosinophilia secondary to dermatological diseases (such as sarcoptic mange), inflammatory bowel disease and pulmonary diseases, all of which may have a hypersensitivity component. Interestingly, atopic dermatitis does not seem to cause a significant eosinophilia in dogs.

How to test for EIC in dogs?

Exercise-Induced Collapse DNA Test

1. Test Highlights:
2. Name: Exercise-Induced Collapse (EIC)
3. DNA Samples: Collected at Home Using Cheek Swabs.
4. Cost: $58 + S&H per Dog.
5. Results: 5 Business Days after Receipt of Samples.

What triggers collapsed trachea in dogs?

The exact cause of tracheal collapse is unknown, but evidence suggests there is likely a genetic component. Certain risk factors may include obesity, heart disease, concurrent respiratory disease, and environmental irritants (smoking, chemical cleaners, etc.).

Why is my dog coughing and gagging all the time?

Respiratory infections, including kennel cough or pneumonia, can lead to persistent coughing and gagging. Dogs with respiratory infections may also display nasal discharge, lethargy, and loss of appetite. If your dog has been exposed to other dogs recently or seems sick, a respiratory infection could be the cause.

What age does IVDD usually start?

Severe damage can lead to entire loss of pain sensation.

In these dogs, average onset of clinical signs is between 3–6 years of age, although x-rays can show the presence of disc calcification by 2 years of age.

What is the 7 second rule for dogs?

The "7-second rule" for dogs is a simple test to see if pavement is too hot for their paws: press the back of your hand to the ground for seven seconds, and if it's too hot for you to hold comfortably, it's too hot for your dog's paw pads, which can easily burn on surfaces like asphalt, concrete, and even artificial turf. This helps prevent paw burns by prompting you to walk during cooler times (early morning/late evening) or stick to grass, as tarmac can get extremely hot even on moderately warm days.
 

How do I strengthen my dog's hind legs?

Hindlimb Exercises You Can Do At Home

1. Slow Leash Walking.
2. Weight Shifting.
3. Unloading of One Limb While Standing.
4. Sit-to-Stand.
5. Incline/Decline Standing & Walking.
6. Walking on Different Surfaces.
7. Cavaletti Rails or Hurdles.
8. Balance Discs/BOSU/Yoga Ball.

Which dog breed is most prone to seizures?

Epilepsy is more common in purebred dogs, including Beagles, Bernese Mountain Dogs, Border Collies, Boxers, Cocker Spaniels, Labrador Retrievers, and Golden Retrievers. Male dogs may be more predisposed to idiopathic epilepsy than females.

What is the rule of 3 for seizures?

The "Rule of 3" for seizures refers to two different concepts: a medical guideline for defining seizure freedom (wait 3 times the longest prior seizure interval) and first-aid steps (Stay, Safe, Side). Medically, the "Rule of Three-To-Six" suggests waiting three times the typical seizure interval to confirm seizure freedom after an intervention, but potentially longer (up to six times) if seizure risk is high, while clinically, the 3 S's (Stay, Safe, Side) guide first aid: Stay with the person, ensure they are Safe, and turn them on their Side for breathing.
 

What dog breeds are prone to collapse?

Exercise-induced collapse (EIC) is a genetic disorder that causes dogs of certain breeds to collapse after a period of intense exercise. The breeds affected are primarily sporting dogs (retrievers, spaniels).

What can be mistaken for collapsed trachea in dogs?

Any disease of the upper or lower airway can be mistaken for tracheal collapse, including a foreign object in the airway, laryngeal paralysis, an elongated soft palate, infection of the trachea, lungs, or heart failure, as well as tumors or polyps.
