Can’t tell if you’re being sarcastic or not but what you’re describing is Terminator. Early models were detectable by dogs because of rubber skin but newer models were cyborgs and had actual human skin and so were not as easily detectable and could hide among the people.

I hate getting pedantic on a side note, but the T-1000s (improved model over the Arnie ones) were detectable by dogs, and they weren’t made of anything human. There’s a scene in T2 where the T-1000 is on the phone with a young John Connor, and John asks why the family dog is going nuts in the background.
