You are lucky Farley is alive and well. Chocolate is toxic to dogs (depending on the strength of chocolate,the size of the dog and the amount eaten). Please be sure to put all chocolate away.
Farley is a youngster who bonded with dogs first - it doesn't mean that he can't bond with you. It just means you have to work harder at giving him good leadership and spending quality time with him learning to bond with people.
Titus will be fine - he just needs to set the bondaries that Farley needs to learn. Right now he treats everyone like his personal play toy and he needs to learn that not everyone wants to be his personal play toy.
Love Them & Lead Them,
