The WCVM Veterinary Medical Centre's Small Animal Medicine Service sees out-patient cases for:

  • physical examinations and vaccinations (visit Pet Wellness)
  • evaluation and testing for inherited disorders (visit Inherited Disorders)
  • routine diagnostic procedures
  • diagnosis and treatment of uncomplicated diseases
  • cardiac evaluation and monitoring during treatment
  • monitoring of patients being treated for a variety of conditions
More complex cases may require hospitalization and more in-depth procedures or testing. Examples of these more serious cases include:
  • disorders causing diarrhea, vomiting or weight loss
  • testing and monitoring of patients with Diabetes mellitus or Cushing's disease
  • radioactive iodine treatment for hyperthyroidism in cats (click here for more information)
  • respiratory disorders
  • congenital and acquired heart disorders
  • anemia and bleeding disorders
  • nervous system disorders causing weakness, incoordination, paralysis, head tilt or seizures
  • immune-mediated disorders
  • kidney diseases
  • cases requiring endoscopy or surgery for diagnosis or treatment
  • wound care and treatment

The Small Animal Medicine Service also operates an emergency service that provides evaluation and treatment of animals with urgent conditions that are unable to wait for the next available appointment. Clinicians are available to see acutely ill, seriously ill or injured animals 24 hours a day, 365 days a year.

Hyperthyroidism in cats: information for owners

Has your cat been placed on a waiting list at the WCVM Veterinary Medical Centre to receive radioactive iodine treatment for hyperthyroidism?

To help prepare you for your cat’s trip and treatment, we have answered some of the most common questions that are asked about the WCVM's treatment program.

Hyperthyroidism in cats: information for referring veterinarians

We have gathered together information for veterinarians who have questions regarding the referral of hyperthyroid cats for treatment with radioactive iodine (131I).

Exercise-induced collapse (EIC) in Labrador retrievers: owner information

A syndrome of exercise intolerance and collapse (EIC) has been recognized in otherwise normal Labrador retrievers.

Investigators from the University of Minnesota (Ned Patterson, Jim Mickelson, Katie Minor), the University of Saskatchewan (Susan Taylor, Cindy Shmon), and the Comparative Neuromuscular Unit at the University of California (Diane Shelton) have been researching this condition for more than 15 years.

We have summarized some of what the research team has learned about the syndrome of exercise-induced collapse (EIC) in Labrador retrievers.

Exercise-induced collapse (EIC) in Labrador retrievers: facts
  • EIC is the most common reason for exercise and excitement induced collapse or wobbly gait in Labrador retrievers that seem otherwise normal and healthy.
  • Most dogs with EIC exhibit a characteristic pattern of collapse starting with rear limb weakness. They may continue to walk or run while dragging their back legs.  EIC collapse progressively worsens as the dog continues to exercise and may even continue to worsen for a few minutes after exercise is halted.
  • All exercising Labrador retrievers will have high body temperatures after strenuous activity.  It is not unusual for both EIC affected dogs and EIC unaffected dogs to have temperatures greater than 107 F (41.7C) after 10 minutes of retrieving.
  • EIC-related collapse is not painful and typically resolves after 5-25 minutes of rest.
  • A severe episode of EIC collapse can be fatal.
  • Most (>80%) dogs that have EIC are observed to collapse at least once before the age of 3 years.  A few genetically affected dogs never collapse – probably because they never experience the right mix of exercise and excitement.
  • Activities involving continuous intense exercise with excitement or stress are most likely to trigger episodes of EIC-related collapse.
  • The only way to know for certain whether or not a dog has EIC is through DNA testing.
  • A mutation in the gene for dynamin-1 (DNM1) causes susceptibility to EIC.  EIC is an autosomal recessive inherited trait, meaning that to be affected (and susceptible to collapse) a dog must have two copies of the mutant gene – one inherited from each parent. 
  • DNA testing for the DNM1 mutation can be performed on cheek swabs, blood, or puppy dewclaws. Results will determine whether a dog has EIC (2 copies of the mutation: E/E), is a carrier of EIC (1 copy of the mutation: E/N), or is clear of the mutation (N/N). 
  • Results from EIC testing can easily be posted on the Orthopedic Foundation for Animals website ( along with hip, elbow, eye and CNM certifications, making the results available to breeders evaluating the suitability of listed dogs for breeding purposes.
Exercise-induced collapse (EIC) in Labrador retrievers: testing

Exercise-induced collapse (EIC) is a nervous system disorder that is inherited in Labrador retrievers, curly coated retrievers, Chesapeake Bay retrievers, German wirehaired pointers, cocker spaniels, Boykin spaniels, Bouvier des Flanders, Old English sheepdogs and Pembroke Welsh corgis.

It is inherited as an autosomal recessive trait, meaning that the causative mutation must be inherited from both parents in order to produce an affected puppy.

DNA testing can confirm that a collapsing dog has EIC. More importantly, testing can be used to determine whether a dog that will be used for breeding is:

  • affected by EIC (has two copies of the causative mutation E/E)
  • a carrier of EIC (has one copy of the causative mutation E/N)
  • clear of EIC (no copies of the mutation N/N).

Centronuclear myopathy (CNM): testing

Centronuclear myopathy (CNM) is a muscle disorder that is inherited in Labrador retrievers. It has been recognized in the retriever community for decades and known as "muscular myopathy." It is inherited as an autosomal recessive trait, meaning that the disease allele must be inherited from both parents in order to produce an affected puppy.

Carriers of CNM appear normal, but they will pass the mutant disease allele on to half of their puppies. Whenever two carriers are bred, there is a likelihood that affected puppies will be born.

Border collie collapse (BCC): information

An exercise intolerance syndrome similar to exercise-induced collapse (EIC) syndrome described in Labrador retrievers has been recognized in border collies and may be called border collie collapse (BCC).

This disorder has also been called exercise-induced hyperthermia and "the wobbles." It is most common in dogs used for working stock but has also been seen in dogs training for agility or flyball competitions and in dogs repetitively retrieving a ball or frisbee.
