Does Pavlov's dogs ring a bell?

Pavlov's dog didn't ring the bell. It just salivated when he heard the bell ringing because Pavlov conditioned him with food when he rang the bell.

Bell, hence the expression "Give me a bell sometime"

Only if you didn't want someone to know the commands you are giving your dog. A lot of dogs are now taught/trained in many different languages so that the "common" person won't know the commands that are being given to the dogs. A lot of Law Enforcement dogs are taught commands that are NOT in English so the dog doesn't get "confused" when it's Handler gives a command during an "encounter" while out on patrol with a lot of people around. Personally my own dogs are NOT given commands in English,they were trained with another language. Also to let you know,my dogs are not German Shepherds,so it doesn't matter the breed of the dog,only how they are trained.

I have one. The Phantom is on the side of the house under the living room window(living room in on 2nd floor). I hear knocking some nights on the wall. There is no plumbing on that side of the house. At first, I thought it was a joke. So while the knocking was going on I snuck down stairs, all the lights where off and looked out the window. Nothing, and it stopped as soon as I got near the window. My dogs never barked either, very strange. I don't think about it much but it still happens about every month or so. I ignore it now.

Think of physical reasons as well.  Maybe barking hurts their throats.  In my lab's case, barking apparently bothers her ears as she shakes her head after barking.\n\nAdditionally, maybe their previous owners used a bark reducing training collar.  One that sends a shock when the dog barks.\n\nFinally, maybe like some people, they just don't have much to say.

I believe there is.  As a long teim animal person, I am positive that our pets for example can tell when we are calm or excited or whatever and often respond to our emotional state.

Of course they do.... Portland Sea Dogs, who have been there for many years.  \n\nThanks for the help, geniuses.

First off, scientists have found that the aluminum hat thing actually works as an antenna and would only make it worse. Now then whenever the dog starts communicating telepathically think very hard on the phrase " No No Bad Dog" then think about hitting the dog on the snout not hard but firmly with a rolled up newspaper.

I believe in God. But that has no relevance on a dogs intelligence. I know that when I say lay down they understand me. When they bark I have no clue of what they are saying. So in a sense they may have one up on me.

No.\n\nCarry a hedgehog as well. That ought to do it.

Yes.  I think that the animals were here first, and just because their brains aren't as developed doesn't mean they don't have feelings.  Animals have every right to be here, if not more.

No, probably not.  It wouldn't yeild any useful data.\n\nBiological organisms are, at least for the purpose of this question, a form of chaotic system.  Since chaotic systems can't be modeled by anyone short of God, measuring animal calls through spectrum analysis wouldn't do you very much good.

No it is a myth dogs have real good hearing and can hear stuff that you do not so they hear it and bark at it.\n\n\nHowever, I am sure there are cases that a dog hears someone that was going to kill someone but was just barking because it heard him.
