She isn't a red brindle -- not sure why it says that... She is a yellow brindle. She could also be called a yellow brindle leopard.

Those are red brindle catahoula pups on the left..

Here is a yellow brindle catahoula


As you can see, there is a very big difference in these two colours.

But the other catahoula does look like a grey patchwork to me. It's an interesting colour, but I prefer it when it is diluted to blue.
