Unfortunately, most of them are also blind, deaf, or both. This is the reason that the
Not every dog with too much white is deaf, so there are probably additional genetic factors which determine whether the dog is deaf. However, if breeders make efforts not to produce puppies with white on or close around the ears they can significantly reduce the frequency of deafness in the breed.
Did you know that dogs with predominantly white coats can be prone to deafness? Not all white dogs are deaf, but approximately 85 different dog breeds have been reported to carry the trait that causes congenital deafness.
Solid black and red coats are the least common coats among Aussie dogs, with solid red being the absolute rarest. The red-colored gene is recessive in dogs, meaning red fur must be present in both parents to make a red-colored pup.
Thus deafness is strongly linked to the white coat colour and blue eye colour, but not all white cats or white cats with blue eyes are necessarily deaf. The variable penetrance of deafness and eye colour may be caused by interplay with other genes and/or environmental factors.
Deafness in Dogs
More than 30 breeds of dogs have a known susceptibility for deafness, including the Australian shepherd, Boston terrier, cocker spaniel, Dalmatian, German shepherd, Jack Russell terrier, Maltese, toy and miniature poodle, and West Highland white terrier. Typically, it is more common in senior dogs.
White is acceptable on the neck (either in part or as a full collar), chest, legs, muzzle underparts, blaze on head and white extension from underpart up to four inches, measuring from a horizontal line at the elbow. White on the head should not predominate, and the eyes must be fully surrounded by color and pigment.
White Aussies are rare today because we have been slowly eliminating the “more white” forms of the white marking genes from our gene pool by not breeding Aussies with more than allowable white (though the preference for white trim on the show dogs does have some pushing the envelope.)
They are often referred to as “double merles.” If these puppies only had lots of white, there wouldn't be a problem. Unfortunately, most of them are also blind, deaf, or both. This is the reason that the breed standards disqualify white dogs.
Congenital hearing loss is mostly due to genetic factors, and these are found to be associated with certain coat colors. The coat colors associated with the highest risk are: white.
Deaf dogs are just as capable and intelligent as dogs that can hear. They just need a little extra time and patience. You will have to learn and teach your fur-baby the different hand signals. And just like humans that are deaf, their other senses are more sensitive.
Cochleosaccular is the most common cause of deafness and is associated with coat color patterns. It is usually seen in dogs with the piebald color genes or merle color gene. It can cause deafness in either one or both ears and is seen more in association with blue eyes and a white coat.
The BAER (Brainstem Auditory Evoked Response) test is used to check the hearing of a dog. The test checks if the brain responds to noise (usually a clicking sound) and is a reliable way to see if a dog is deaf and to what extent.
Blue eyes, resulting from an absence of pigment in the iris, is common with pigment-associated deafness but is not, in and of itself, an indication of deafness or the presence of a deafness gene; however, in several breeds (Dalmatian, English Setter, English Cocker Spaniel, Bull Terrier), dogs (and cats) with blue eyes ...
Very genuine, very loyal; expressing Australian values; Australian. This derives from a British English sense of true blue, recorded from the 17th century with the meaning 'faithful, staunch, unwavering in one's commitments or principles; extremely loyal'.
The Australian Shepherd is one of a few dog breeds that commonly have two different colored eyes, called heterochromia. Aussies might have any combination of brown, blue, hazel, amber, or green eyes. Some Aussies even display more than one color within the same eye.
Are Black Australian Shepherds Rare? Only solid black Aussies are rare, since this breed typically has a multicolored coat. The other coat patterns in the black category are much more common.
A dog that cannot see or hear may be less independent and could experience harsher circumstances in their life than one that can rely on all their senses. With that said, there's no reason for such a blind dog to enjoy life any less than one that can see or hear perfectly.
While the once widely believed theory that dogs see everything in black and white has been proven false, the truth is that dogs see a color spectrum similar to that of humans with red-green colorblindness, says the American Kennel Club (AKC).
As in white cats, the genes responsible for coat color, eye, and ear health are not causally linked, so white and albino dogs are not necessarily more likely to be born blind or deaf. However, a rare genetic combination, known as “double merle,” does carry inherent health risks.
Your Aussie will bond to his family and be protective of and loyal to them. Many dog owners are surprised to learn that even though Aussies have strong guarding and herding instincts, they are sweet and cuddly indoor dogs that can even be kept in apartments.
Some Australian Shepherds tend to “grin”, not to be mistaken for baring their teeth, when feeling silly or goofy. It's a sign of appeasement! A dog will grin if it senses you his owner needs to be calmed down or when they are excited by greeting people or guests.
Aussies can also be split into four categories based on the four fabulous colors of the dog's fur. These categories are Black Australian Shepherd, Red Australian Shepherd, Red Merle Australian Shepherd, and Blue Merle Australian Shepherd.
