Which brand of dog biscuits is the most brightly coloured?

We've been advised by the park ranger to use dog biscuits for stream speed measurement. Are there any brands which have a range of reasonably bright colours, so that they are clearly visible? Or are all dog biscuits like that?

Do you mean small, kibble type dog food? Bakers has lots of colourants so that should work. But are you throwing them in the water? They're quite absorbant I think, so would disintegrate quite quickly.

Pets at home do a large bag of dog biscuits (treat ones) that are brightly coloured.

Generally colourants aren't great in dog food so look for the cheaper, poorer quality brands.

And that might be the first time I've ever made that recommendation!

Also, if the food absorbed water, would that slow it down and skew your results?

I did hydrology at uni, I'm desperately trying to remember how we did it!!

I got Bakers , thanks for the suggestion! They won't be in the water too long so it should be ok.
