Adult Rottweiler showing agression
He wandered up on our property as a pup, our son took care of him for 5 yrs... he has bitten my husband and growls at him when he gets near him.
Our son recently left, and could not take the dog with him. We can not get near him, without him growling or acting as if he wants to attack.
We have not been around the dog a lot....just recently. We don't want him put down, but need help, or suggestions.
This is a very difficult and sad situation, and I feel for all of you.
You have no history on this dog prior to your son adopting him so it's impossible to know what his parents temperaments were like and whether his behavior is purely a result of improper and inadequate socialization or a combination of genes and upbringing... or whether he's reacting out of aggression or fear (I would tend to think it's fear-based)
As he's growling and has bitten your husband there's obviously a danger and you need to get some professional help. I'd recommend searching for Rottweiler rescue organizations in your area and calling them for help first. I don't know where you are, but if you check my Rottweiler Rescue Groups page it will hopefully help you.
Also, reputable Rottweiler breeders may know of an organization or individual who is able to help, or a no-kill shelter or even the ASPCA are options.
Rottweilers rarely get second chances and a situation like this needs someone who is familiar with the breed and able to accurately evaluate the problem and the dog himself. Otherwise this could end in heartbreak. As your son is the only one this dog seems to trust, perhaps you can get him involved in helping get this resolved.
I wish I could help more but I pray that you can find someone to help and that there is a happy ending to this story. I wish you all the luck in the world.
