Perhaps this may help.

"Despite the unique karyotypic features of the dog, the sex-averaged rate
of recombination across the genome (0.97 cM/Mb) is within the range of other
characterized mammals (0.5~1.1 cM/Mb). Genetic map-based estimates of
recombination rate are available for two additional carnivore species, house
cat (~1.1 cM/Mb; MENOTTI-RAYMOND et al. 1999) and silver fox (0.6 cM/Mb;
KUKEKOVA et al. 2007). While large differences in map quality and coverage
preclude detailed comparisons, the rate of recombination in dog is clearly not
an outlier among carnivores. Although fine-scale recombination rates evolve on
short evolutionary timescales (PTAK et al. 2005; WINCKLER et al. 2005),
the dog genetic map adds evidence for more rigid evolutionary constraints
on broader scale recombination rates (MYERS et al. 2005; DUMONT and PAYSEUR

I'm looking for references for conversion of bp to cM for the dog
genome. The rule of thumb for humans is 10^6 bp ~ 1 cM, but dogs have a
lot more LD, so the conversion would probably be different.
