The owner is happy that  they greet realtors.

     If the dogs were illegally running loose, contact Animal Control.  If you are on private property, you may not have a case.

I learned when I was young, NEVER RUN, face them, step toward them and they will turn and run.  And it does not hurt to growl at them under your breath.

Even big guard dogs are cowards when approached right.

I teach this to my foresters for when dealing with Wolves and Bears, so far nobody has been eaten.

Stand still and tall and stare them down

I would normally bark or bite back, the dogs don't understand much more than that.

I wouldn't stay around long but at the same time I try not to show fear. Sometimes I yell back and tell them to hush and they do.

I would be scared, hopefully you were able to get away without getting bit or anything.

I normally mail material like that Jenny Ho 

Jenny Ho Dogs can be very protective of their owners. I would have asked the owner first then proceeded cautiously.

My father was once bitten by one.  After that he carried mace.

My take, carry dog treats and use those first before going to the mace/pepper spray.  Beyond that is really a personal call.  I'm not sure I could go further than that unless I was being actively mauled.

Why dog treats?  Because dogs love them and they taste better than we do (or at least better than I do).  It is also the #1 way crooks get around guard dogs, since very few dogs are trained to only take food from their master.

Never run or show you are afraid..they can sense it!

Carry dog biscuits with you if you walk a neighborhood.

I get along with all dogs and can read them. Stand your ground, and stand tall  and speak calmly toward them, then EAT 'em!~

I have had this happen more than once. The answer is always found in the moment if you stay in the moment that is. Fear interferes with answers

Try and remain calm and hope the owner has some degree of control!

#1. Contact the first animal (dog) trainer you can find. Learn how to identify the friendly dog and the other kind. Know the visual signs. Rottweilers do not announce their intent.

#2. Pay attention

#3. Measure the value of the effort. If the house looks like Sam's post, you may choose to skip this one.

#4. When door knocking I have the luxury of taking Sasquatch along. His role is to intercept all distractions. He has mowed the grass while I talk to the owner, played catch with the kids and allowed the dogs to jump on him and not me. His presence has a way of moderating how some curmudgeons choose to respond.

That is why i dont go door to door any longer. Dog bite to the wrist. 

reason to buy a gun!!! 

parked and reading

You do have to be still and stare them down. But your situation is exactly why I don't door knock or go to properties I haven't been invited to.

I face them down - I am armed and ready to take those dogs out should the need arise!

Avoid the dogs.

Depends on the dogs and the location. Avoid putting yourself in those type of situations. Running might not be good idea. Try to stay calm. They might just want to lick you and get petted. Dogs bark and that doesn't mean they are mean. if they don't bite, let them smell you, slowly pet them, tell them to sit, etc.

When prospecting , carry dog biscuits !

If you were on my property my dogs would in fact bite you. They don't leave our property without a leash though.

Wow!!  I'm wondering why the homeowner didn't 'have control' of their 2 dogs - why they chased you, with that person watching?  Very scary Jenny Ho.  They could have told you their dogs were not friendly and that they didn't want your hand-outs, as opposed to having you think that they were going to attack or bite you.  To me this means the owner was 'not in control' - the dogs were. 

Not a fan of big dogs unless they are Labradoodles.

If you have the time grab any aerosol-type in your purse and spray it in their face. Aim for the eyes but they hate it in their nose too so accuracy isn't critical.Hairspray works almost as well as mace as long as it's an atomized spray (not pump).

Bark back (the bark is worst than the bite). I am just throwing a little humor in Jenny, hope you are ok.

dogs for sure sense fear, but some dogs are clearly not worth confronting

The last thing you should do is run.

If you are at the owner's front door, be as brave as you can.

If you are walking down the street carry some type of protection.  I know people have Mace, Bear Spray or Wasp Spray.

Keep in mind that the dog's owner probably won't want to list with you if you spray his dog.

Good luck.

Don't go back :) Seriously, glad that's over. Others have said it, you have to be confident (I know that's hard) but that's your best defense against a barking dog. Most, that's all they are is all bark, no bite. But for the few who will attack, your odds are better being strong about it. SHOW YOUR TEETH!
