Piebald Spotting in Chihuahuas
What colour Chihuahua is that in the window? Chihuahuas are most often seen in a light brown colour called “fawn,” although they may come in a range of colours. Chihuahuas with patches of any hue in the Chihuahua range are known as Piebald Chihuahuas.
Acceptable Chihuahua Colours
Despite the fact that fawn is the most common hue, the Chihuahua is a multicoloured breed. Their coats may be every colour a dog can have, including sable and white. Chihuahua coats may include brindle or merle patterns in addition to the white spotting pattern that produces piebald spotting.
Chihuahua coats may be plain, white-marked, or parti-coloured (white with patches of colour). The same genetic component termed the “white spotting” locus produces both little spots of white and huge quantities of white that conceal the body colour — piebald. The piebald spotting gene is recessive to the solid coat colour; that is, piebald spotting is caused by two identical genes, while a solid coloured coat is caused by just one gene. If there is any colour showing through the white blanket produced by the piebald spotting mutation, it is most often on the dog’s head and tail base. Any colour or pattern in a Chihuahua’s coat may be covered by the piebald spotting gene.
Deafness, Piebald Spotting And Blue Eyes
Congenital hereditary deafness is often linked to the gene for piebald spotting. Blue-eyed dogs are prone to deafness in certain breeds, such as the Dalmatian. Deafness is most often seen on the side of the head where the blue eye emerges. That is, if a dog has a blue eye on the right side, the right ear will be deaf. When a dog has two blue eyes, both of his ears are usually deaf. This characteristic has not yet been linked to the Chihuahua. It’s worth noting, though, that the AKC Chihuahua standard considers blue eyes to be a “severe defect,” while the UKC standard advises breeding only dogs with dark eyes.
Piebald Spotting Vs. Merle
Many of the breeds with the piebald spotting gene also have merle-producing alleles. One such breed is the Chihuahua. Both the piebald spotted gene and the merle gene have been linked to the development of deaf pups. Piebald spotting and blue eyes are both recessive characteristics, while the merle coat pattern is caused by a dominant gene. So far, there is no evidence that a dog with both piebald spotting and merle coat patterns has a higher risk of deafness, even if a dog with two merle genes may have a higher risk of deafness.
