My mistake. You said the dog has fear aggressive, and indicated possession and territory aggressive. I'm not sure what "full blown out aggression" needs to look like. Obviously, we are defining aggression differently. I would consider a dog that growls and snaps to have aggressive intent. I guess you want a long post.
1.About how old is the dog?
2.Do you have any idea of what brees are in the mix?
3.How many times has the growling/snapping occured?
4. When did it first occur?
5. Who or what is threatening or aggresive behavior directed towards?
6. Is the behavior increasing in frequency or intensity?
7. Who is around when the growl/snaps occur?
8. What has been done so far to try and correct the behavior?
9. What is the make up of the household - other dogs, humans, other pets, children?
10. Does the dog know and obey any other obedience commands other than sit, come and off?
11. What do you mean when you say the dog "has been given complete run of eveything" in the house - Is there a specific behavior problem associated with that freedom - ie house soiling, chewing, etc?
12. When was theh last vet visit and what for?
13. Is the dog on any medication?
14. What is the dog fed and how many times a day?
15. Who feeds the dog?
16. How long has the dog been with the current family?
That will do for now.
