MDR1 is a genetic mutation that is found in some breeds of dogs, including Australian Shepherds. The mutation affects the expression of a gene called multi-drug resistance 1 (MDR1). This gene is responsible for helping to regulate the absorption, distribution, metabolism, and excretion of certain medications, which can be dangerous for dogs with the mutation. As such, MDR1 testing is important for owners of Australian Shepherds to understand their dog’s health risks and prevent potential side effects from certain drugs.
**Common Myths About MDR1 in Australian Shepherds**
MDR1 is a gene mutation that affects the ability of some Australian Shepherds to process certain drugs. As a result, these dogs can have dangerous reactions to certain drugs that would be safe for other breeds. Despite this, there are a number of misconceptions about MDR1 in Australian Shepherds.
Myth 1: All Australian Shepherds have the MDR1 gene mutation.
Fact: Only a small percentage of Australian Shepherds carry the MDR1 gene mutation. The exact percentage is unknown, but it is estimated to be between 10-20%.
Myth 2: Dogs with the MDR1 gene mutation cannot take any medication.
Fact: Dogs with the MDR1 gene mutation can take certain medications, but they must be prescribed by a veterinarian and monitored closely.
Myth 3: The only way to know if a dog has the MDR1 gene mutation is to get a DNA test.
Fact: While a DNA test is the most accurate way to determine if a dog has the MDR1 gene mutation, there are other tests that can be done to determine if a dog is a carrier of the gene. These tests include eye exams, physical exams, and blood tests.
Myth 4: The MDR1 gene mutation is only found in Australian Shepherds.
Fact: While the MDR1 gene mutation is most commonly found in Australian Shepherds, it has also been identified in other breeds, including Collies, Shetland Sheepdogs, and mixed-breed dogs.
