Description of a Merle:
EYES: Often are blue, 1/2 blue
or just may have a tiny speck of blue in them
Look at your dog under close lighting.
It has been reported that merles can also have brown eyes.
But other sources say that there should be a tiny fleck of blue in
the iris.
Even though it may be hard to see.
Rule of thumb says if your dog has blue eyes even though you can't
see the merle pattern, chances are, it is a merle.
*Note Most cocker pups have blue or green eyes at birth, but change
to brown by 3 months or less.So don't automatically think merle until the
age their eyes turn.if they stay blue or have flecks of blue, then you
will know..
COLORING: Can
be tan pointed. Comes in all colors and varieties; black, brown, buff,
red, sable, partis.
PATTERN:It
is an incomplete dominant dilution
gene.
Generally the color will be a lighter shade
than the actual color should be.
You may see a tiny spot or several areas
where the color is of the same shade but darker.
The over all appearance can show a marbling effect.Or
it can have patches of different colors together.
The pattern is not spread evenly over the coat, but leaves patches
of undiluted color scattered over the dog's body. These areas can
and often do include the nose, lips, and eyes. Sometimes they will have
what they call a butterfly nose, which means the pigment in the nose is
spotchy and leaves areas still pink, when the dog is older.
The color white will mask any merling, so be careful. Buff and sable
can also mask merling.
Appearance At Birth: The merle gene
DILUTES
areas of color.
A pup will appear as a lighter version of the color it would have
been if not bred to a merle.
There could be spots that are the actual darker color. For instance.
A blue merle, is a diluted black dog. Instead of the entire coat
being black,
the coat will be diluted to gray (blue).
But you may see spots of black on the coat. Maybe just on the ears
or the tip of a tail. ALWAYS look at the pups under good and bright
light.
If the dog is brown, the same thing applies. The coat will be a
lighter brown, with the dark, normal color of brown patches.
If the dog is buff, it is very hard to tell, and looking
at the dog in bright light is essential and go through the coat very carefully.
Sometimes
these are referred as cryptic or hidden merles. But true cryptic merle
are generally rare.
Parti coats can be hard to tell too. Look for dilution and
darker color of the same color.
Sables can also be very hard to tell, with the merle pattern
and the sable mixed together
Make sure you check ear tips, tails,nose,lips...everywhere for the
merling.
The color white will mask any merling, so be careful.

Breeding: Merle is an incomplete DOMINANT
gene
A merle will always produce at least 1 merle pup
no matter WHAT color it is bred to.
A DOUBLE merle will produce an entire
litter of merles, along with the possible lethal double merle gene.
Pups that are not merle out of a merle breeding to a non merle cocker,
do
not have the lethal genes and are considered safe.

Description Of a Roan:
EYES: Brown
*Note in some English Cockers, some roans can have a blue eye or eyes,
but it's not the norm.
COLORING: Blue Roan, Brown Roan,
Sable Roan , Orange Roan, Lemon Roan...and also can be tan pointed. Roans
are considered partis.
PATTERN:The roan gene is expressed
(seen)only in the white
areas of spotted dogs. The roan has the base coat color interspersed
with the white
Another example would be:
If X was a black hair and 0 a white hair the roan pattern
would look something like this:
X0X0X0X0
Sometimes you'll see two or more hairs of the same color together but
it is pretty much mixed.
It can be more of a 00X000X0X
where roaning is lighter,
but it isn't in a pattern of patches like it is with merle.
Appearance At Birth: They can look roan
at birth, but generally look like a regular marked parti with some
smudging possibly on the muzzle or feet.
They appear to look like a parti. (WHITE
with perhaps
some solid colored markings)But within a few weeks the roaning will become
more and more apparant..The roan gene is expressed (seen)only in the white
areas of spotted dogs. The roan has the base coat color interspersed with
the white

Cockers, click

As you can see, this does NOT look like merle.
Thanks to Coreen for this photo
Often the paw pads in a baby roan pup will have a dark
halo around them.
And you can see the "smudged" look on the chin and feet
in this photo.

Breeding: Roan is a Simple DOMINANT
gene.
You cannot get a roan unless one of it's parents are roan. It is
NOT recessive.
It does not skip generations. Breeding roan to roan does
NOT have any health issues associated with the gene. |
