I had a golden retriever. She never bit anyone When my two year old cousin put her hand in tge dog’s ear, there was some serious snarling going on which caused me to never allow dogs and kids together again.
They don’t mix
A pit bull will go right in for the kill
But no dog likes a toddler
They’ll protect it, knowing that it’s owners/feeders value tge child more than the dog, but people stupid people mistake that for some kind of affection
