hello and welcome to BYC,there are always exception's to the rules,some ppl have pet dog's who don't eat their chicken's,i grew up with dog and chicken's whe never had a problem,i also have an 7 year old shih tzu that forages with the chicken's and wait's at the coop every night to see the safe to bed,she's truly wonderful,the chicken's pay no mind to her and she even lets them roost on her and they are always stay near her when she is out there,so good luck and i'm so glad you joined
