Breaking dog from chasing cats
I will be talking to the rescue group about this as well, but thought I would get some opinions from the good folks here as well.
Trinkett (greyhound) and Rana (cat) seem to be settling in well in the house. Rana is still occasionally hissing, spitting, and swatting at Trink, but that's really died down, and mainly seems to be when Rana is frustrated at not getting to go out. But other than that, life inside is mostly quiet.
The new problem is outside. I had Rana and Trink out this evening. Trink was going to the bathroom and nosing around the yard when Rana saw a squirrel up on the fence. Rana being a high prey-drive cat, she tore off to go run up a tree towards the squirrel (and no, I don't know why she thought going up that tree was going to help her get the squirrel, since the fence was no where near it.) And Trink... decided to go after Rana. I yelled at her and she stopped, while Rana doubled back to the porch and inside, thankfully untouched. She doesn't react to the cat outside when they are both just walking along, or sitting around. I figure that seeing a small furry body running at full speed was just too much of a trigger for Trink to resist.
So, do people think that this can be trained out of Trink? Or is it an just instinct too strong to resist, the same way Rana can't resist trying to catch squirrels? I'd be willing to work with her, but the problem is that I can't predict when it's going to happen since it depends on the local wildlife. The other option would be to only allow them out separately, or to have Trink wear her turn-out muzzle when they are both outside. She's not thrilled at the muzzle, but it would keep the cat safe, and provide a distraction to Trink.
In case it matters, this does definitely seem to be an indoor/outdoor thing. Inside, Rana can still keep the dog from going through a doorway just by sitting in it. So it's a bit shocking to see Trink take after her outside. But I know that some dogs will do that, so it's not entirely unexpected.
Any thoughts?
