I have a 1 year old chihuahua/dachshund mix. He is super cute and pretty much everyone who comes into contact with him loves him.
One problem...he has issues when encountering dogs larger than him. My parents have a 13 year old mini-poodle and they get on really well (my pup mostly runs circles around my parents dog but there's never any aggression). Our neighbors have a small chihuahua and a lab mix puppy (probably about the same size as my dog now but clearly he will get bigger) and when we run into them outside all is good.
Larger dogs...that's another story. Today we encountered a young lab mix and my neighbor and I let the boys get to know each other (smell each other and what not). While doing so the other dog kinda stepped over my dog (my dog was underneath him). Well Simon (my dog) freaked out. Started barking and growling crazy.
Why does this only happen with larger dogs? Does my dog have an "I'm little" complex? I'm relatively new to this dog-mom stuff so please forgive the stupid question.
