Our Tibetan Terrier is 14 months old and still nips when he's over excited. It's like a switch flips and he tips over into being aggressive. It's so quick that we cant recognise the triggers.
We would remove ourselves but we can't, nor put him in a pen, because he then bites harder. DDog has begun to bark aggressively when he's lunging and nipping. It's happening quite frequently.
Any ideas of behavioural strategies? It's beginning to worry us.
