Beg To Differ
I beg to differ with your statement "Silver labs don't have any health problems associated to their color, nor their life expectancy any different".
Silver labs DO have health issues associated with their color. It is extremely irresponsible of anyone to make a statement such as the one I have quoted above.
Color dilution alopecia (CDA) is one of the "silver" color related genetic condition that a silver lab can suffer from all affecting the quality of their life.
CDA causes multiple skin and coat problems including:
alopecia with permanent hair loss (either partial or generalized)
a spare, coarse and dry coat lacking any protective oil
a lacking of a traditional double coat
sores and condomes to skin with secondary bacterial infections (requiring antibiotic treatment)
Body temperature regulation issues related to heat and cold exposure. Sunburning and hypothermia are of real concerns.
Inability to be able to participate in any hunting activities.
How do I know all of this? Because I have a silver lab who suffers from CDA. When researching the silver lab we believed a lot of the positive commentary. We have come to live with the fact that not all that commentary was accurate.
