Does brindle coats develop as a puppy ages?

Hi, sorry me again with more questions  

Pebbles's parents looked to me like two blue and white dogs (it was dark outside when we saw them and under a not that great light) lol. However
We have noticed that since we have had her (4 weeks now) Pebbles' coat has been changing. At first at 9 weeks old she was mainly blue and white (on the chest) with a tiny amount of what looked like sable/light tan coloured stripes down her romp that were mainly visible in the sunshine.
Four weeks on and she has more and more of the light coloured stripes all over her coat and even the top of her head.
Is this developing brindle pattern on her coat normal?

One of my friend told me brindle dogs are born with the pattern and it is clear from birth.
I am  

Anyone with an explanation?
Cheers

Some dogs' coats do change slightly as they mature, so it's possible that the brindling will become more apparent as she grows!

Perfectly normal - Blue is a dilute of Black Brindle , it is not physically possible to have a pure black dog and the brindle will develop as they get older , Tilly for instance had little tiny flecks here and there that you would never notice , now she has lots of brindle patches

Thanks that is reassuring to read  

I think i worry way too much about our new doggy!  

Bruno is mainly blue too but has two little light brown patches on his sides which are becoming more noticeable as he grows. It's a part of him and his loveliness!

Pebbles and Bru sound very similar

A local blue puppy bitch is developing brown stripes too, quite an arresting combination.

Lynda you are not talking about my Pebbles are you?   We are also in hampshire

Farnborough?

Ah nope. Southampton  

Darcy was nearly all black when we got her. Now she's coerced in brindle

I see it is more common that i thought. There was me half believing i had a strange pup on my hands.
I will also tell my friend she was wrong  

Hi was being nosey and reading this post just wondering why it isnt possible to get a pure black dog x

yep, harvey is 95% white but has a brindle head and couple of patches, but when we got him at 8 weeks they were jet black but got very very brindle as he got older!

Brindling is a colour pattern & not a colour. So, it will change depending on age/maturity.

All brindle dogs will change to an extent from puppyhood to adulthood, blue/fawn especially. Many blue ot fawn dogs will appear solid as pups but will develop brindling as they get their adult coats.

Something to with genes, not having the gene for it, I think??

Ohhhhh that's interesting so if you have a black puppy does it mean then that it is a cross. Sasha is 90o/o black with a white chest she used to look brown when she was much younger now she is jet black ??????

I think so yeah if it was pure black, no white and no brindle markings, so Sasha is OK with a white chest  

Sure if I'm wrong about this someone more knowledgeable will correct me!  

lol im sure they will. I wonder why you can get black and a bit of white but not all black surely if it was a gene thing sasha wouldnt be black at all. This is intriguing me im sure there is someone that knows the reason why out there . I would love sasha no matter what colour or breed she is even if she is a cross it was those sad eyes that got me x

i'm sure someone told pure black pup are normal still born  

Really thats sad x

From a friend I have just asked

A study was undertaken some years ago, to determine the colour/pattern genes within the breed. All of the seemingly 'black' dogs studied were found to carry the brindle gene. It's simple enough to guage by the fact that mating two 'black' staffords can produce stripey brindle puppies, if they were indeed 'black' this would not be possible. A Staffordshire Bull Terrier who appears to be jet black is simply so heavily marked with brindle stripes that the base colour underneath the stripes is completely covered over.

When we got Roxy AKA Rodney she was black, now she is brindle at 6 months.

Sasha was brown when we picked her up now she is jet black shes even logged as brown and white at the vets but its interesting all the same thanks Dave for the info.

Another answer

It's, basically, because the gene for a true black coat does not exist in our breed. It's like asking, why xan't a Rottweiler be brindle?? Costhe gene for brindle patterning is not in the breeds dna.

Vinnie was solid colour as a pup but over 2 years has developed quite a lot of brindle, I tell him he is turning ginger!!  

So you are saying sasha may be a cross then dave?????

Another interesting fact on Brindle

Brindle is not even really a colour, brindle coats are created by the brindle parttern gene. Basically, a red stafford inherits the brindle pattern gene which causes the darker pigment on the coat to be arranged in stripes on top of the red. .....brindles are basically reds, with stripes on top

Not at all Jan , just saying as much as you think the majority of her coat is jet black she will have some brindle on her somewhere even if its the tiniest bit and unnoticeable . The white has nothing to do with it that's just a patch as you get patches on reds or blues and brindles , same as you also get pieds , certainly not indicative of a cross

So is Darcy red with black stripes or black with red stripes  

so many colours its really interesting you are all so knowledgeable on this forum I would never have thought that she wasn't black. I didn't see Sasha's mum and dad she looks like a staffie to me but what do I know lol. I dont mind what she is was just intrigued by the post

she's a staffy Jan , just have a really really close look on her coat and you will find something there but you may have to look for a long time

lol she doesn't keep still long enough for me to have a look she very energetic these days

You will find very few truly black animals. It's just not a natural colour in most cases.

Even black wolves aren't actually black, and the colour itself is a mutation. They're grey wolves with a melanistic colour variation due to a cross with a dog, which most likely had the colour mutation. Even in domestic dogs, the black colour is a mutation. It's thought that the mutation appeared for some genetic advantage (and worked, as the colour is dominant and very much apparent in today's wolves), but they haven't pinpointed exactly what it is yet. It has been suggested that the colour itself isn't important, but rather the positive effect the mutation has on immunity.

Oh we are in Southampton!! Our Jasmine is 13 weeks now. She is blue and has a few more fawn brindle stripes coming through, Wherebouts are you in Soton?? I feel a puppy walkies coming on:)

My Stan looked black as a pup but the orange marking etc (brindle) has shown itself as he's matured. He's black brindle with a white bib etc.

It's funny you should say that as there's another forum member that has the same as you.

When you get a min, pop along here and say Hi to everyone:-

Black is basically a heavy striping. Your dog is red! It's all in the genes. White is just a flek that can be any size.

Tommy was black when we saw him at a few weeks, when we went back at 8 weeks, he was black and brindle lol.
