Thyroid Disease - High Risk

The Cocker Spaniel ranks #13 among all breeds for autoimmune thyroiditis prevalence. There is a high risk of obtaining a dog that will develop thyroid disease. For this reason you should make sure you, or your breeder, are testing all dogs before breeding.  It may even be a good idea to test dogs that you don't plan on breeding so that any instance of disease can be traced back to breeding pairs and eliminated.

Other Health Problems

With the popularity of Cocker Spaniel as a pet and gun dog there has been a significant amount of backyard breeding that has lead to some serious health conditions in many Cockers that are not purchased from reputable breeders. Even within some of the purebred lines there are some minor health issue, but these are seen in many breeds of dogs. Some of the more serious health concerns are:

  • IMHA ( Immune Mediated Hemolytic Anemia ) - the immune system attacks the blood cells, resulting in serious blood loss from the body in the urine and typically death if not treated immediately.
  • Eyes - glaucoma, cataracts, entropion and ectropion, progressive retinal atrophy (PRA) resulting in eventual blindness.
  • Skin - allergies, seborrhea, lip fold pyoderma all which can lead to irritations and skin infections as the dog scratches and rubs the area.
  • Otitis externa - ear infections, common in any dog with a folded ear.
  • Phosphofructokinase deficiency - destroys red blood cells and leads to anemia and muscle degeneration and pain in movement.
  • Cardiomyopathy - heart conditions such as disease or muscle development problems.
