Cooper's separation anxiety has greatly improved in the past several weeks. Him and I have had sufficient time to bond and now we can begin the process of working on his protective streak. Ive decided that the usage of a Gentle Leader will give his owners and myself the confidence to begin the process of teaching him to tolerate strangers in their home and yard. Cooper is an excellent student. I don't think he really wants to be dominant over strangers, but without guidance gave himself the responsibility of being over protective. I am suspicious that this is the reason he was probably abandoned in the first place. This behavior was most likely present and rehearsed well before he was ever adopted by his new family. Cooper adjusts well to new people provided you are firm with him and work on obedience for the first few minutes of a strangers arrival. I look forward to working with him and his family more in the next several weeks. Myself and his owners are extremely encouraged by his advancement!
