Yeah ignorance is bad.
I brought Kali to a meeting when she was 9 weeks and 3 days because I didn't want to leave her alone. My breeder told me I was lucky nothing happened to her and now I learned my lesson - they have to be 12 weeks and have 2 parvo vaccines because you take them out.
But after that by all means do take them out - they will get used to go with you and meet a lot of people. And that will make them bark less when confronted with strangers
