A pit would have a better chance than three chihuahuas. As I posted earlier little dogs aren’t so tough and a puma considers little dogs and cats food not threats.
At the Compound my pit, min pins and Pomeranian would alert me as I am the one with the guns.
Kitty would have died.
Pretty much what you can depend on them to do, as long as they are behind a barrier where they can detect, without being accessed, such as in the house.
Then it is up to the mifwic to stop the threat.
Our remaining jrt "thinks" he is bad shiite, but he does have a keen sense of hearing still, and a very loud alarm bark.
Unless he hears the yotes, then he stays on the bed and growls a lot!
chuckles to you...I’ll be a pack of those little ankle biters would sure confuse even a puma...:O)
