This is Taco's new strange behaviour. I swear, he's such a character, he's constantly coming up with something else to entertain us. When we scold or reprimand Buster (our Golden Retriever) in any way....maybe by just saying "Buster, go lay down!" or somehting similar, Taco jumps up and growls and barks and attacks Buster. It's just like he's reprimanding him because he got in trouble. Has anyone else ever heard of this? Is that really what he's doing? It sure seems like it to us. And, it's so strange, I'm not sure what I should do about it. So far, I've yelled at Taco for attacking Buster, who is an 80 lb. wimp and lets a chihuahua boss him around. lol Should I be doing something else?
