Yesterday my bullmastiff growled at my son when he hugged him. This worried me but I don’t know if I am making too much of this or should there be concern, my dog didn’t snap at him and didn’t make any other aggressive move towards him. Hendrix, my mastiff has not been aggressive towards other children before so I am not sure how to handle this. I sent him out side after I scolded him and when I let him back in the house I asked my son to try and hug him again and Hendrix responded well and licked him. My son is in no way aggressive or mean to animals we have two dogs and he loves animals. Any suggestions on what I should do or what not to do?
