i have two yellow labs, both very well behaved because i took the time to train them properly. this girl i've been seeing off and on got a 1/2 shih tzu 1/2 jack russell terrier about 7 months ago and this thing is HORRIBLE. whenever i'm at her place, this thing is just the definition of annoying. it jumps up on you, barks at everything, gets scared really easy and pisses on shit, and a ton of other annoying crap. anyways, she has asked me to train it, because she sees how good my dogs are. i told her no matter what i do, she has to stop treating it as if it is a person and be its owner. her reply is "i know but its just so damn cute" wtf? so i have had this thing for the past few days (she had to go out of town) and i have some concerns. it doesn't respond to anything except food (it has her trained to get treats rather than her training it). but when i train my dogs there is a certain amount of force used. no abuse, no kicking, nothing like that. stern slaps to the butt or nose if they do something bad, or a thumb in the mouth if they chew or bite. well today i caught it chewing on the leg of my kitchen table (no damage done yet, caught him early as i was watching him) and he got a swift smack on the nose. the damn thing bit my hand, and out of reflex with the other one i smacked it and it went flying nearly halfway across the room. now this thing is scared to death and when i try to come near it it fucking hisses at me and tries to bite me. i'm really tempted to just beat this things ass and hopefully instill some dominance in it, but i'm not sure if that would even help. anyone have any suggestions. i LOVE animals, especially dogs, but i feel like this thing thinks it is in charge of people and that is a BAD thing to have a dog feel. i don't want to hurt it, but i really do think that asserting some force to show dominance is what it needs. also, i might go pick up a shock collar and try that out. has anyone used one of those? this dog needs to be trained for its sake, the girls sake, and for other people's safety around it. i'm not just gonna hand the dog back to this girl and be like "sorry that thing is a lost cause" without really trying. also, on a side note, she won't take it to a dog trainer (she had a dog die at one when she was growing up and thinks they abuse them or something) so that is absolutely out of the question, and she is currently way too busy with her job to do a owner/trainer thing with herself and her dog. i don't feel obligated to do this, i just don't ever back down from a challenge. thanks.
