Conclusion

This study indicates a trend that brachycephalic breeds have higher visual acuity than dolichocephalic breeds and show a visual acuity threshold considerably higher than what has previously been established in daylight.Hence, skull shape does not only correlate with ganglion cell distribution (Mcgreevy et.al. 2003) but could also be a trend with the dog´s perceived visual acuity. To establish more conclusive results and if this pattern is also present in dim conditions, more research is needed especially with more dogs and several representative breeds.
