Shih Tzu randomly attacking cats
My fiance and I found a 3 year old female Shih Tzu in the park behind our house in early June. We kept her, got her shots. We also have multiple cats (8 total but only 3 come inside the house) as we feed strays. At first she had zero problem with any cat whether they were in the house or on our property. Recently though she has been attacking the cats who stay indoors without warning, she attacked (multiple times) a pregnant cat, and has gone after my male cat while he was on my lap. I've put the indoor cats on the porch in fear she'll hurt them. We don't know what to. We don't want to get rid of her but we might have to.
