I have a Pitt Bull and a chihuahua. They never had any issues until today. Today my pug was licking my chihuahua and my chihuahua was growling gently at the pug for him to stop. Then the pitbul come to intervene and attacks my chihuahua. Some time goes by and an almost identical situation happens. But the 3rd time we watched carefully as the pug was not involved. The pitbul approaches the chihuahua and we watched as he sniffed towards the chihuahuas mouth then almost like a switch the pitbul attacks and goes straight for the neck. If we didn’t intervene it’s certain he would kill the chihuahua. What is the meaning of all this? Does my chihuahua have a mouth Bacteria that the pitbul has deemed worthy to terminate?? I just don’t understand why it’s all started now and not any other time before.
Could someone please help?

Whatever started it, if you don't separate them and keep them separate from now on, you're going to lose your chihuahua. You'd probably be smart to keep the smaller dogs separate from the larger one period. I know of a couple of people who have lost small dogs to larger ones that "they always got along with before." The size difference means anything from an expression of momentary anger to a full out fight between 2 dogs of similar size is fatal for the small dog. In this case if it's happened 3 times, it's going to continue to happen.

Complete separation always isn't a lot of fun. I know because I've got a dog who would kill another if she could, and I keep at least 2 gates between them at all times. I'm ridiculously careful about it, but it keeps everyone safe.
