You have to weight the pros, and cons on socialising a puppy before fully vaccinated. While I don't take mine to places where a lot of dogs gather.
I do take them to a lot of other places.
My daughter carried June around Bass Pro shop as a tiny puppy. Although she was never put on the floor, they took pictures with the Easter bunny. She went with us for the family gathering on Easter.
She went with us to visit friends, and be sure to invite friends over.
Plenty of running dragging a check cord behind her, in out if the way, off the beaten path places.
Not all those who wander are lost.
Life is just a leap of faith.
Spread your arms and hold your breath and always trust your cape.
Two things define you. Your patience when you have nothing, and your attitude when you have everything.
