I have a concern regarding my 7 year old golden retriever/chow mix. Recently we have taken Fret from my father inlaw because he can no longer walk him. My problem is that Fret is aggressive when it comes to his food bowl. It is the only thing that seems to bother him. He is a big pushover with everything else (eg. Kids, other dogs etc). When we come near him when he is eating he will growl at us. I have been told that he has been that way all his life. I am wondering if I should be concerned with this behaviour or not. I have a 6 year old son who knows to stay away from Fret when he is eating. I just worry if this could progress into something worst. I feel I should let you know that even though he growls he has never bitten anyone or anything. Any advice would be appreciated.
