Otto is a senior dog who I adopted in 2012. When we first got him, he showed aggression to my 8 year old niece. Since then he has really calmed down and listens well. He is around my 2 year old often and has never shown any signs of aggression, though we never leave them alone together. He is a very sweet, cuddly, low maintenance dog who likes walks but is happy to hang out inside, save for the occasional bathroom break. In his current home, he roams the yard without ever going past the fence. He comes when he is called and responds well to all commands. I believe his past aggression was due to him being overprotective of me when meeting new people. The niece he was aggressive with his moving in with us, so we can no longer keep Otto. I'm heartbroken and looking for a good home for him. He is 65 lbs and completely up to date with vets visits.
