Sister chromosome exchanges are recombination events that occur between homologous chromosomes and are often the result of exposure of the cell to DNA damaging agents.
Cross over, or recombination, is the exchange of chromosome segments between non sister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.

Answer:

Explanation:
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.
