I have a problem with a dog that has suddenly turned aggressive towards 
 srangers
 There is a new baby in the house but he is ok with him and the rest of 
 the family just srangers,so much so that the vet had to sedate him to 
 give him his jabs as she could not put a muzzle on him.
 I was hoping if you could tell me why he has suddenly got agressive as 
 he had been alright before and what the best way to proceed with 
 him,does he just need for someone to take up the alpha role with him as 
 i dont think that has been done yet or are the other things to try 
 first. He is a 1 year old golden retriever.
 Any ideas will be much appreiciated kind Regards
