Bio: Toby was attacked by a 80lb dog during the early second year of his life and as a result is very timid when he meets strangers, other dogs or humans. Toby is a couple months past his second birthday now. Once he has smelt the stranger he is becomes totally playful with humans. However he is reserved to which dogs he will interact with. I'm wondering how to go about correcting this timid behaviour. As Toby was a completely friendly and playful dog prior to the attack. I was considering getting a second aussie, good idea bad?
