Because the merle gene is dominant, the dog really only needs one copy of the gene to produce this coat. When a Border Collie has two copies of the merle gene, there can be many complications in regard to health. These conditions may include deafness, mild blindness (abnormal small eyes) and overall poor health. The merle can be broken down
black, blue, fawn, gray, white. Patterns. bicolor, merle, sable, tricolor. Other Traits. cold weather tolerant, good hiking companion, requires lots of grooming, strong loyalty tendencies. There's been no better ambassador to the collie breed than Lassie, the beloved dog from the 1940s silver screen who saves the day again and again.
So, to wrap that all up, yes. Border Collies make extremely good additions to many families, permitting you have the active lifestyle they need to stay fit and healthy. These intelligent dogs will thrive on family connections and having a job. So, if you have the space and the time, this dog can be one of the most rewarding breeds.
The basic colour of an animal’s fur is lightened and grained in places. The eyes of Merle dogs are also unusual: blue, white or blue-white. Typical Merle breeds include the Australian Shepherd, Collie, Chihuahua, Dachshund, Border Collie and Great Dane. The selective breeding for this colour is often accompanied by ocular and auditory defects.
Puppies with (MM) genes tend to have health issues, particularly with their eyes and ears. The exact reasons why the two merle genes together cause these problems remains unclear. It is known that merle coated dogs have a slightly increased risk of hearing problems, possibly due to the Silv gene.
As highly active dogs, a healthy adult Border Collie should have at least 2 hours of high-quality exercise per day. The amount of exercise should be tailored to fit their health, for example, a more energetic dog should have more exercise and an older, less mobile one will need to have less. Splitting this exercise between at least 2 different
So far, this is OK. Apart from the prejudice against white dogs, we wouldn't particularly care. But the double merle dog has a high probability of serious medical problems. Most of them are completely deaf; many have bad eyes with reduced vision.
The Veterinary Genetics Laboratory (VGL), in collaboration with Dr. Niels C. Pedersen and staff, has developed a panel of short tandem repeat (STR) markers that will determine genetic diversity across the genome and in the Dog Leukocyte Antigen (DLA) class I and II regions. This test panel is useful to breeders who wish to track and increase
A ‘double merle’ is a merle that has two copies of the merle gene, this is to be avoided at all costs as there are numerous health issues associated with this genetic combination, mainly deafness, poor eyesight and general poor health and development. A double merle will often appear excessively white coloured and may have abnormally small
First and foremost, you should never ever breed two merle Border Collies together. Breeding merle-to-merle will inevitably cause deafness as well as vision problems in future generations, because of genetic conflict. Breeding merle-to-merle Border Collies is only done by irresponsible and ignorant puppy farmers.
Common health problems. Collie eye anomaly (CEA) and epilepsy are considered the primary genetic diseases of concern in the breed at this time. CEA is a congenital, inherited eye disease involving the retina, choroid, and sclera that sometimes affects border collies. In border collies, it is generally a mild disease and rarely significantly
6 days ago · 1. They are prone to severe back and eye problems. Because of their weiner dog shapes, dapple Dachshunds have a higher risk of Intervertebral disc disease (IVDD) than other dog breeds. In fact, 19-24% of all Dachshunds are affected by the condition. IVDD is very painful and can even cause paralysis.
Border Collies can also be affected by other eye diseases including glaucoma. This is a condition which causes a build-up of fluid and pressure in the eye, leading to damage of the optic nerve and the retina which can rapidly lead to blindness. While it can be caused by a dog’s genetics, glaucoma can be triggered by other conditions like
How much is a blue Border Collie? Color can also affect the cost of a Border Collie. Black and white Border Collies are the cheapest, while rare colors like merle will cost more. You could pay $4,000 for a rare blue merle puppy, while a black and white puppy will typically cost you around $1,000.
