Posting here as, although we had dogs growing up, I don't have experience of this situation.
A family friend has recently acquired a young dog (I think roughly a year old). Was living at the breeder's before that.
She told me before it arrived that the dog was a bit shy, but actually it seems to be guarding her all the time, and growling when anyone comes near. My kids are well trained in not approaching dogs, being calm around them, but they're getting growled at whenever they go near the owner.
I'm concerned this might be an accident waiting to happen; am I overthinking this, or am I right that something needs to change here? (For what it's worth, while our friend is a loving owner, she doesn't seem to think about dog ownership (inc previous dogs) in the way I mostly see on here.... I'm 100% sure no training is occurring).
Really grateful for more expert advice!
