Like SoCalyorkiLvr said I also like to give people the benefit of the doubt.
This week I was at Petco and saw 3 young lady's came in and one put this fur ball on the floor that started walking. I was leaving but I turned around and had to ask "What is that?" one girl replied "It's a girl Palm... she is 8 wks, I just got her". Then I notice the doggie was eating or licking something off the floor

. I tried not to raise my voice and watch my words but in my head I screamed!!
I quickly told her to pick her up not to let her eat, lick or touch the floor. I explained to her that other people bring their dogs and they poop on the floor sometimes and I went on to explain about puppy shots, illness, along with her not touching other animals and going home without washing her hands and told her to do a lot of research on the net.
She was very thankful for my info. Then I notice something black behind the pups ear , I pointed out what I saw and told her the pup had fleas.
A lot of people don't know much or at times anything about the dogs they get, I was one once. Now, I try to help them just like those many that helped me.
