Aggressive Mini Schnauzer
I have an 11 month old Mini Schnauzer who is selectively aggressive. She can be like this when she is tired or her paws are touched, both of which are understandable. What concerns me is how she growls at people for no reason, or bites aggressively. She bit my neighbour who was reaching for her shoes, and bit someone making repairs to my fridge. She's met my neighbour on numerous occasions and has been introduced on regular occasions. With the man fixing my fridge, he was on the floor looking under the fridge while I held a light to help. I'm not sure if my mini thought I was being harmed, but she went after the repairman. She has been put in a kennel afterwards, but the behaviour continues.
