My dog is now 11 months old and her face is starting to change more into an adult appearance. So the eyes are seemingly getting a bit smaller, the cheeks bigger, etc.
It can be frustrating hearing people talk when they see you and your dog approach, but let me tell you, for every dismissive/mean look/comment I get, I get at least 10-15 friendly comments, people asking to pet her and just absolute in love with her.
I knew what I was getting myself into. I had no dog experience before and I still remember my first encounter with a "pit hater": I was training at Home Depot, she sat to let people pet her (she was 7 months back then). There were 3 people around us, talking to me, petting her. Then an old guy came by with his cart, looked at her, then at me and asked me what breed she is. "Pit mix", he turned away while saying "oh hell no, get this beast out of here".
I was hurt, she is my dog, she is an amazing dog, friendly to everything and everyone, but some people don't care. And that's what you have to realize.
These people don't care. The dog could get up, make them a coffee and serve breakfast, they still wouldn't change their mind. Don't ever take it personally! (even though I sometimes still do

Because mostly I think it is unfair to my girl to talk/think bad about her, just because she has "the looks".)
I'm not trying to educate anyone, if someone wants to know something, I'm more than happy to have a conversation with them, but I won't start preaching.
Also, I have met a lot of pit (mix) owners by now myself and there are some weird people (as commented in a different post, one lady is really on the trip that "they need to know who the boss is").
In the end I don't need anyone to love my dog, my husband and I do and that's what counts!
