Creating cone mapping model for domestic dog in visible light

I am using mica toolbox to try and quantify the camouflage of a little native Australian bird in its native habitat from the perspective of a native predator (likely bird with tetra chromatic vision) and an invasive predator (ie. fox or cat). Through using a full spectrum camera we established that there isn’t anywhere on their body that reflects in the UV. This meant that we could use a visible light camera to get pictures of them in their natural habitat.

As I used a Canon R7 (which isn’t already listed in mica toolbox), I photographed and measured an x-rite colour chart so that I could generate a cone mapping model from a chart. I would like to generate this model for both the blue tit bird and a domestic dog. Creating the model for the blue tit was easy as there is a blue tit LMS 400 – 700 option, however, for the domestic dog it is only 300-700 which means I get an error when I try and use the XRite Passport 400-700 chart reflectance spectra. Is there an easy work around in this situation, alternatively, is it possible to load the domestic dog spectral sensitivities without the uv? Thanks so much
