When humans taste or smell, receptors unique to each nerve cell detect the chemical and send signals to the brain, where many cells process the message to understand what we are smelling or tasting. But a bacterium is just a single cell, and it must use many different receptors to sense and interpret everything around it.

It was a little hard to see your cross, so I made another one and it is attached below.
So what you are looking for is the likelihood of an offspring with a phenotype of brown spots and short tails.
Without using the Punnet, we can already deduce that it is 0%. This is because brown spots are recessive, and the only way a brown spotted dog would have this trait, is each parent had at least 1 recessive allele for this trait.
So the expected genotype for brown spot would be:
bb
Only one of them has this, so they cannot have brown spots.
