I have a rat terrier.
I could not see your facebook pictures, so can’t comment on them.
Mine is not a barker at all, probably barks maybe three times a year and with reason, something is going on and it is not a real bark, more a gruff “something is wrong, come see”.
She is great around the horses, never bothers them and they ignore her too:

Mine was supposed to be my next agility dog, but has had a torn ligament in a hock since she came here as a 11 week old puppy, that our vet, that is an orthopedic specialist, didn’t want to touch.
So, she is ok, just not quite right, so no jumping.
She is a great companion, loves everyone, especially kids, although she is a bit shy also, is 5 1/2 years old now.
At her size of 11", she is portable, so can go with me much anywhere, goes in the tractor and four wheeler and is always around, watching what goes on.
She is a mouser and rabbiter, but calls back very well.
She is the right dog for me now and, since I am hard of hearing, nice to have around to alert to any going on around here.
I agree, rat terriers, toy terriers and such crossed between little bitty dog and terrier are not for everyone, just as poodles or beagles are not.
Some breeds are novice and careless and mayhem friendly, some are not quite so forgiving of any but the right environment and care for their idiosyncrasies.
In the early 1900’s, practically all farms had some rat terriers running around, they were very handy to have around for rodent patrol and entertainment.
Without so many farms any more and not so wise to let dogs run around without supervision, rat terriers have made an uneasy move to pet and companions.
It will take some breeding to get them where most become purely pets without a job and be happy with that life, not find some other entertainment like destroying things or barking non stop.
