I've recently adopted a little dog from a friend of a friend who is emigrating . He seems fairly chilled out and happy to be with us but although i was assured hes used to children and has a great temperament he has growled at my children a few times now . Yesterday ds1 (16) was being gentle with him, stroking him and when he went to move him he let out quite an angry growl . He wasn't doing anything different to what i have done with the dog . I realise hes probably not fully used to us yet but maybe he doesn't have the temperament i was led to believe he had , what would you think ? I haven't had a dog since i was a child but i don't ever remember being growled at . should i be worried ?
