Fascinating

It is fascinating learning new words, and their meaning, with regards to caring for animals. 
'the word Epigenetics!

The study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself. 

So where does this word apply to breeding dogs or owning dogs.  Its basically contamination of chemicals, be it bleach, disinfectants, soap powders, fabric conditioners, and so on, the chemicals with in can be absorbed by the dogs body and humans body and alter the code.  Wow!    Our water ways now have a huge percentage of flea and wormer chemicals being found.  This is indeed worrying.  As not only are we putting it on dogs fur and it having an effect, but its also seeping into our water systems. 

It starts with the effects our animals are subjected too in the housing of the parents, creation of life forming inside mum when cells matter. Walking your bitch on a road way and coming into contact with chemicals on paws, noses, and if they lick something.  Can in fact have an effect on the health of the puppy to be. 

The whole thought process is just now blowing me away with the conclusions

Its certainly me worth now researching much more now.
