Chihuahua’s?
I have one. Nice dog, doesn’t do much, a bit independent but not a trouble maker.
I had a min pin years ago. Loyal to a fault, an 8 pounder. I always said that if that min pin was 40 pounds it would be dangerous. Terriors are like that.
Problem with Chihuahua’s is you can never tell if it’s biting you or not. I had one attack my leg, I think. It’s teeth got stuck in my pantleg and we had to gently free him as he growled his mighty death threads. Pitt bulls will remove massive chunks of flesh and limbs so it’s much easier to tell when they attack you.
