Q: Without opining on the rightness or wrongness of his choice, a lab, most medium dogs, can run around 30 mph. That's 44 feet in a second. A fairly big yard depth. One second isn't a lot of time to do assess, decide and react, much less do multiple things, until the dog is on you once it starts running.

A: No

Q: Susan L. Fenton suggested I "should try adopting a zygote" so I would learn "the difference between a zygote and an actual person."  

Fenton is obviously ignorant about what is known as surrogacy. An introduction can be read online at: https://en.wikipedia.org/wiki/Surrogacy  

The following quotes from the "Surrogacy" Wikipedia article are telling.

QUOTES: "Gestational surrogacy (GS)
A surrogate is implanted with an embryo created by IVF. The resulting child is genetically unrelated to the surrogate. There are several sub-types of gestational surrogacy as noted below. ...
Gestational surrogacy and donor embryo (GS/DE)
A donor embryo is implanted in a surrogate; such embryos may be available when others undergoing IVF have embryos left over, which they opt to donate to others. The resulting child is genetically unrelated to the intended parent(s) and genetically unrelated to the surrogate."

In a GS/DE, a "genetically unrelated" embryo (previously a zygote) is being legally adopted.
