The English Cocker Spaniel comes in a wide variety of coat colors: from deep black to warm gold, from parti-color to roan patterns.
Solid-colored English Cocker Spaniels
The solid-colored variants of the English Cocker Spaniel form the foundation of this versatile breed’s color palette. Unlike the parti-colored and roan cockers, the solid cocker, as the name suggests, has primarily one dominant color, although a small white patch on the chest is completely acceptable according to the breed standard.
Black, red, gold and brown explained
First there is the black English Cocker Spaniel, which in its purest form (homozygous) has a deep raven-black coat. However, when a black cocker also carries a gene for another color (heterozygous), the coat can show subtle shading or a rusty sheen. This is because the dog, in addition to the dominant black gene, also carries a gene for, for example, red, brown or tan.
The red Cocker Spaniel is another beautiful example of a solid-colored variant. This color is caused by having two recessive red genes (ee). Although the skin and eye pigment in red cockers is usually normal, some dogs with this genetic makeup have a less pigmented nose.
There is also the golden Cocker Spaniel, which usually has black pigment. A golden cocker with brown pigment also occurs but is particularly rare. The brown (also called liver or chocolate) Cocker Spaniel has brown pigment everywhere — from the coat to the nose, eyelids, lips, paw pads and even the nails. This color is genetically represented as ‘bb’.
What is sable and why is it rare?
The sable color variant is a fascinating pattern in which brown hairs have black tips. In fact, sable is a pattern where the tan markings become ‘wild’ and spread over the coat. In puppies the dark hair is often still dense, but as the dog ages the dark hair decreases and the lighter sable color becomes more dominant.
Sable is not necessarily rare as some claim: it is simply not bred as often in the show world. This explains why this color variant is less common.
Black & tan and chocolate & tan variants
Finally, there are the solid-colored cockers with tan markings. When both parents carry the tan gene, variants such as black & tan or chocolate & tan (liver & tan) can occur. The tan color can range from straw-blond to hazelnut and is found in specific locations:
- Two distinct spots above the eyes
- On the side of the muzzle and on the jaw
- On the inside of the ears
- Between the upper arm and the forechest
- On the forelegs from toes to wrist
- On the hind legs from toes to hock
- Under the tail
In red cockers the tan pattern may be present, but it is often difficult to see due to the low color contrast.
Multi-colored and roan colors
What are roan patterns?
Roan, or ‘schimmel’ as it is called in Dutch, is a distinctive color pattern where the base color is mixed with white hairs. This creates a speckled or marbled appearance. Unlike a spot or a simple color combination, roan consists of an even mix of pigmented and white hairs.
Genetically, the roan pattern is determined by the R-locus. The roan gene (R) is dominant over the non-roan gene (rr), which means a roan Cocker can be a carrier of the piebald gene, but a piebald Cocker can never be a carrier of the roan gene. This makes roan the most dominantly inherited pattern among multicolored English Cocker Spaniels.
Blue roan, liver roan and other variants
The English Cocker Spaniel colors within the roan spectrum are amazingly diverse. The most well-known variants are:
- Blue roan: a mix of black and white hairs that gives a bluish effect
- Liver roan (brown roan): brown hairs mixed with white
- Orange roan (orange roan): orange hairs mixed with white, can have either black or brown pigment
- Lemon roan (lemon roan): the most recessive roan color, lighter than orange
In roan patterns the dark spots are usually located on both sides of the skull, cover the ears and appear around the base of the tail. In addition, spots can occur anywhere on the body. A striking feature of roan Cockers is that their paw pads are always fully pigmented – black in blue roan and orange roan with black pigment, brown in liver roan and orange roan with brown pigment.
Parti colors: black-and-white, red-and-white, lemon-and-white
Besides the roan patterns there are the parti or ‘parti-coloured’ English Cocker Spaniels. These dogs have larger patches of a particular color on a white background. The most common combinations are:
- Black-and-white (with black pigment)
- Liver-and-white (brown-and-white, with brown pigment)
- Red-and-white (may have either black or brown pigment)
- Lemon-and-white (with black or light brown pigment)
For parti Cockers it’s important to know that the skin under the white coat is pink, while the skin under the colored areas is pigmented. In addition, parti Cockers have paw pads that are partly colored and partly pink.
Ticking versus roan: the difference
Although ticking and roan may look similar at first glance, there are important differences. Ticking consists of small colored flecks on an otherwise white coat, whereas roan is an even mixture of colored and white hairs.
Genetically, ticking sits between roan and parti in the dominance hierarchy: it is recessive to roan but dominant over parti. The T-locus, which corresponds to the usherin gene (USH2A), determines the development of ticking.
An important difference is that with ticking large white areas can occur, whereas this is not possible with roan [1]. In addition, ticking only develops after several weeks – puppies are born without ticking, and the small spots appear gradually.
The genetics behind the colors
Main color genes: A, B, E, S, R, T
The genetics of the English Cocker Spaniel are determined by several genes, each playing a specific role in color expression:
- A gene (Agouti): Controls the tan markings and determines patterns from black to sable
- B gene (Black/Brown): Determines whether the dog produces black or brown (liver) pigment. Black (B) is dominant over brown (b)
- E gene (Extension): Responsible for red color in English Cockers. A dog with two recessive red genes (ee) is red
- S gene (Solid): Determines whether the coat is solid-colored or has white markings
- R gene (Roan): Causes the roan pattern, where R is dominant over r (non-roan)
- T gene (Ticking): Creates small colored specks in a white coat
There are also other genes such as C (pigment depth), D (dilution), G (graying), and K (black dominance) that also affect the final coat color.
What is the difference between phenotype and genotype?
When understanding cocker spaniel coat colors, the distinction between phenotype and genotype is essential:
- Phenotype is how the dog looks physically – the visible color and patterns
- Genotype is the genetic makeup that does not always fully manifest in the appearance
For example, a dog can be phenotypically black while genetically a carrier of brown. In this case the dog has a Bb genotype (black carrying brown), but a black phenotype. This explains why two black cockers can suddenly produce a brown puppy.
How recessive genes reveal hidden colors
The phenomenon of ‘hidden colors’ is due to the action of recessive genes. A recessive gene only expresses itself when a dog has two copies of it (homozygous). As long as a dominant gene is present, the recessive gene remains ‘hidden’.
A striking example of this is the brown factor. A black cocker with genotype BB cannot produce brown puppies. However, a black cocker with genotype Bb (carrier of brown) can, when paired with another Bb carrier, produce brown puppies (bb).
The same applies to the red color. This is only visible when a dog has two recessive e-genes (ee). Two black dogs that are carriers of red (Ee) can together have red puppies.
Moreover, one gene can mask the presence of another. This is why a color can remain hidden for generations and then suddenly appear in a litter.
Eye and nose color with different pigments
In the English Cocker Spaniel the color of the eyes and nose is closely linked to the coat color. This link is determined by the same pigment genes that influence the coat color.
How eye color changes in puppies
A surprising fact for new owners: all English Cocker puppies are born with blue eyes, regardless of their eventual eye color. The final color develops gradually. Puppies with black pigment (black nose) are born with dark blue eyes that change directly to dark brown. In contrast, puppies with brown pigment (brown nose) undergo a remarkable transformation – from blue to green and eventually to various shades of brown or hazel.
This color change is not random but follows a predictable pattern. In chocolate-brown puppies the blue iris color can vary from mid-blue to dark-blue shades before gradually changing.
Brown pigment and hazelnut-colored eyes
It is genetically impossible to breed truly dark eyes in a dog with brown pigmentation. According to the breed standard, English Cockers should have “dark brown or brown, never light” eyes. However, for liver colors, liver roan, and liver & white, “dark hazelnut-colored eyes in harmony with the coat” are permitted.
Dogs with liver or liver roan coats therefore have hazelnut-colored eyes that harmonize with their coat color. This hazelnut color lies on the color spectrum between dark and light brown, with a characteristically multicolored iris – often dark green or olive green around the pupil and medium brown or light brown on the outer edge.
Relationship between pigmentation and expression
Iris color is determined by the amount and type of pigments. Appearance variations arise from differences in the ratio between two types of melanin: eumelanin and pheomelanin. Additionally, a notable characteristic is that the inner rim of the iris (directly around the pupil) is usually darker than the outer rim, in both black- and brown-pigmented dogs.
These subtle color differences contribute to the expression of the English Cocker Spaniel. Most black-pigmented Cockers have very dark brown eyes that appear almost black, which contributes to their soft yet alert look. When the coat color is diluted, the eye color will proportionally follow, enhancing the harmony in the dog’s appearance.
The Cocker Spaniel Club emphasizes the importance of following the breed standard regarding eye color and warns against trendy deviations such as blue or green eyes, which are not within the standard.
Breeding and inheritance of color
Breeding for specific English Cocker Spaniel colors is a fascinating process that requires precise knowledge of color genetics. In the past, rare colors such as sable were not valued and pups with these colors were sometimes even eliminated at birth, because it was suspected that other breeds were in the pedigree.
Which combinations produce which colors?
The color outcomes in breeding are predictable when you understand the genetic principles. When both parents are black without the recessive brown gene, you will get only black pups. However, if both parents carry the brown gene (Bb), theoretically 25% of the pups will be brown (bb). With a brown parent (bb) and a black carrier (Bb), about 50% of the litter will be brown.
What does it mean to be a carrier of a color gene?
Being a carrier means that a dog possesses a recessive gene without showing it. A black cocker with the genotype Bb has a black coat but carries the brown gene. These carriers are crucial for maintaining color variations in the English Cocker. When breeding two carriers, there is a chance of pups that do express the recessive trait.
Color changes from sun and age
Black cockers can appear duller when they fade in the sun, while roan patterns often become more pronounced with age.
