So as most people may know by now, I got myself a cardigan! He's 4 years old and came from a show home. The old owners showed cardigans and show/breed French Bulldogs. He was one of 7 dogs and low man on the totem pole. The female cardigan and all 4 Frenchies made a habit of beating him up. Because of this, he has some fear aggression. He and Franklin are doing very well together because Franklin is just the cutest friendliest little guy on the planet! Lol. Anyway, my issue is with larger dogs (and the cats). My parents have a very sweet submissive lab and Truck (the cardi) keeps attacking him. If the lab is laying down, Truck is ok with him or if Truck is on the couch and the lab is on the ground, that's ok too, but if the lab and he are both standing then Truck attacks him. What should I do in this situation? I was letting it go at first because the lab doesn't react and will even go so far as to lay down and get to Truck's level, but now Truck will snap at him without being provoked, just whenever the lab is looking like he MAY come in Truck's general direction. I'm not worried about my lab reacting, but I am thinking about when Truck is introduced to some of my friend's dogs. At least 2 of my friends have dogs who WILL NOT allow another dog to attack them and it may result in a fight. I really want to try to build Truck's confidence, so best ways to introduce him to larger dogs? Do I allow him to snap or do I stop him? He is VERY responsive and will stop if I tell him to. Since he is a very submissive dog, I am of the idea that maybe I should stop him from attacking a dominant dog because its only going to result in him fighting and then getting even more scared. 

He appears to have some separation anxiety as well, which is odd based on his breeder's description of him. I think he is just really liking all this attention and doesn't want to end up out in a kennel again or in a crate so he gets super clingy. I am going to have to crate him for school, and so far when I put him in his crate he whines and barks when I leave the room. He can't bark while I'm gone because I live in an apartment. I made him sleep in his crate last night in my room, but should I begin leaving him for short periods of time NOW so when I do have to leave him for school on Tuesday he won't freak out as much? 

And last question, I guess he is a toy, towel, bed destroyer......ideas on good toys to put in his crate to keep him busy while I'm in school? I need toys that I don't need to supervise him since I will be gone at school. The owner never gave him Kongs bc she was afraid he'd get his bottom jaw stuck in the hole and she said no rawhides because he will bite off and swallow big hunks. So I need safe distraction/toy ideas for when I'm gone.
