Thereof, should you breed an EIC carrier?
Also remember that not all dogs that test as “effected†exhibit symptoms of EIC. It is important that two carriers, not be bred together or a carrier bred to an affected dog. These combinations will produce dogs with EIC.
Furthermore, what is EIC clear in dogs? The EIC DNA test results will verify one of the 3 possible genotypes for the dog we have tested: A CLEAR result shows that the dog has inherited two normal genes from its parents and will appear to be normal. The dog will not develop EIC and cannot pass mutated genes on to any offspring.
Keeping this in view, how common is EIC in dogs?
EIC is common in Labrador Retrievers, and now that we have identified the mutation we can test for the condition. Current data shows that 30% to 40% of Labradors are carriers (with one copy of the mutation) and 3% to 13% of dogs are affected (with 2 copies) and susceptible to collapse.
Is EIC in dogs fatal?
Although most dogs recover quickly, within 30 minutes, severe episodes of EIC can be fatal. Dogs affected by the condition often experience numerous recurrences, although their gait and behavior return to normal between episodes.
