Epigenetics: How Environment Shapes Our GenesThe burgeoning new science of epigenetics offers a cornucopia of insights some comforting, some frightening. For example, the male fetus may be especially vulnerable to certain common chemicals in our environment, in ways that damage not only his own sperm but also the sperm of his sons. And it's epigenetics that causes identical twins to vary widely in their susceptibility to dementia and cancer. But here's the good news: unlike mutations, epigenetic

Great rope for dogs that destroy all their toys
Style: 5 KNOTS
So this product is not dog proof but man is it higher quality than others on the market. One of them is a shredder, anything she can get her paws and teeth on she’s ripping apart with all her might, it’s impressive if a stuffed toy lasts 5 minutes. We have tried lots of different materials and toys and this thing is great. It’s not saturated in drool and does not smell after they play all day. It is a large heavy rope so would be cautious if your large dogs likes to thrash. Our big boy doesn’t and it’s too large for our medium sized dog to thrash. Might be a little pricier than others but the extra money is well worth it. 85 lbs rottie mix and 25 lbs terrier mix in the video, we were just moving in so ignore the boxes lol

Great rope, but not for aggressive chewers
Style: 5 KNOTS
This is a great rope, but if your dog is a aggressive chewer, don't buy it. My Doberman chews everything, she destroyed this rope into many pieces, after only having it for 3 days.I swear she would chew iron into pieces. Now she has only bones to chew on....

New Rope for my Pit Bulls
Style: 5 KNOTS
When I received this from Amazon delivery my pit bull mix went crazy on the rope, and she chew on it for the longest time. Then, I played keep away but that lasted a short time. The rope is very strong and long for me to play with my pit bull mix she wants me to play tug a war with her. She will win every time, I do enjoy her every day, makes me happy that she mine.
Price is very reasonable and color was very good and lasted a long time too.
I buy again soon as she wear this one out.

Not for aggressive chewers
Style: 4 Styles Set
These were ok for a short while. But with this aggressive chewer we have they shred and the threads get hung between her teeth. Had to start throwing them away 😕
