DAYUM my boy reacts fast: we were on the bed enjoying our morning snuggles, I was holding his paw while he drifted off to sleep and a tiny quiet bark was heard way out in the distance, very faint. Before that dog was done barking my boy had sprung up and dived off the bed to run to the RV cab (largest window) to investigate. I only realized what was going on because my girl raised her head and her ears stood to attention. My boy got caffeinated Chihuahua reaction time 😂
