So sorry to hear of your frightening experience. I know how scary it is, as my pup Bailey was attacked by a larger dog and it took me and him(but particularly me!) a while to get over it.

It was so frustrating, as before the attack, I had spent a lot of time socialising him with dogs, big and small and he is such a friendly chap.
I agree with what others have said, that you should meet up with other friendly owners and their friendly dogs as soon as you can. I was lucky that after our horrid incident, some local kind people I know (who had heard about the attack) were walking in the enclosed field we visit and deliberately changed their route across to meet us, but made it seem like a light-hearted, casual encounter, so Bailey could approach the situation on his own terms. Meeting up like this certainly helped and your plan to meet up with dogs you all already know is a positive start.

It is also definitely important not to pass on any stressy feelings you have (so hard I know - I became very good at acting for a couple of weeks after the attack!), as our dogs are so good at picking up on these things, aren't they?
But I'd like to reassure that Bailey and I are fine now and he is still our waggy, happy, cocker. There is nothing wrong with being wary sometimes, as there always be untrained dogs and untrained owners.

Just don't let this experience spoil happy times with your dogs,

to you, Freya and Coda,
