I have recently adopted a beautiful mutt, now named Jordan. I found that guessing her possible genetic tree has become a bit of a fixation for me.
By looking at her for the last month and watching her basic tendencies I am guessing at some point there was collie (she parti-eyed, a saddle-sable and white coat, she's loose eyed but has a border collie look to her face) and most likely a pointing spaniel (comparatively large webbed feet, a natural point, and a bound reminiscent of a Springer.) She is from the country, likely a pig farm the shelter said by the way she smelled, so there may not have been ever a breed dog in her line.
It's not this that I am writing about though but the fact that her teats (which are obvious since she must have had a very recent litter before being abandoned)are asymmetric, 5 on the right and 3 on the left. I have found very little on this phenomenom in web searches.
Does any one know how common this is and if it is likely to occur in some breeds than others?
