My own fault. I was walking the dogs to the river, had them off lead. As I rounded the corner, I saw a man down by the river with a dog on a lead. A terrier.
Instead of putting my dogs on their leads, then asking him if she was ok with other dogs, I called out first, by which time, just as the man said 'actually she's the one who's trouble' my dogs had reached her.
I called Patch, pretty much in vain. He was being snarled and snapped at, so was 'in the zone'. His response was to growl back. He didn't bite, and thinking about it, if he wanted to, he well could have, because he wasn't on the lead.
The man scooped his girl up, who was still snarling and snapping in his arms, and Patch jumped up a couple of times to try and reach her, still growling.
He didn't resist me finally getting hold of his collar and putting his lead on, and didn't snap at me when I did so.
Lessons learned:
- Lead on immediately when another dog is sighted, so that introduction can be controlled and if hostile, I can simply lead him away.
(slightly longer term)
- Teach to come to me when he sees a dog. Clicker and treat should achieve that, I think.
- Ask people if dogs are friendly after putting lead back on
Anyway, after all that, I was pondering the situation, and thinking 'what would I want him to do?'
It's probably a bit unreasonable to expect a dog not to growl/snap back if another dog is intent on taking a chunk of him, isn't it?
