Hello Aidan,

What would you do in a case where a dog becomes extremely aggressive towards any dogs or cats (not humans) that go anywhere near his toys, food, leashes, bed or area where it is laying down. This 2 yr. min. poodle formerly lived with 8 other rescue dogs, including an aggressive neop. mastiff before being adopted by its present owner, who has had him since September 2008. The poodle currently shares his home with a 9 yr. old greyhound and 4 cats. The poodle has attacked the greyhound and a visiting puppy in the last month and will growl at the cats if it approaches anything the poodle values. If the poodle is placed in its crate it will growl at any animal that approaches its crate.
Thanks for your help.
