Backstory: Sister in law lives 30 miles away. Her next door neighbor's daughter (17/18) said she wanted a dog. Mother said "no". Low & behold, a couple weeks later, daughter picks up a dog from someone in a parking lot somewhere and brings it home. Dog gets tethered to tree outdoors. As the story gets to me, that is his life....chasing butterflies and laying about. Oh, then daughter tells mother that she (daughter) has joined the army. So Mom didn't want a dog....daughter brings dog home and then joines the Army..... AND GOT FLUNKED OUT at boot camp. (this girl must be a doozy)
Sister in law felt bad for dog so brought him here to farm sometimes to let him at least RUN and get some energy out.
Long story short.... Rufas has been with us now for call it 8 months. I affectionately (and I mean that word) call him "Crazy Boy"
I'm told he's a border collie. He's got a bobbed tail (if that means anything) He is fast as the wind, very VERY strong (about 35/40 pounds) and you can just SEE his intelligence.... he really is an intelligent dog once you start working with him.
Issues seem to be he's very (we think) territorial. He gets along with all the local female dogs.... but bring a male dog in (sister in law has a male and our next door neigbor has a male) and he goes into red mode. (hence "crazy boy")
If anyone comes to visit OTHER than sister in law, he will go bezerk. He will snap at anyone (other than us so far) but rather than trying to bite them it appears he's more nipping at them with his front teeth.
He had a guy stranded on top of his trailer using the tractor as blockage between he & Rufas.
Brother in law came to visit....he knew about Rufas and was prepared with a plan. He came with extra layers of clothing on, came in wearing welders gloves.... rufas went at him and he "defeated" rufas by holding him by the throat on the ground until Rufas realized that he lost. Within 10 minutes, Dan (brother in law) was taking Rufas out on a leash with HIS dog (female Pyrenese sp?)
Fortunately she's about 2 1/2 times bigger than Rufas so can fend him off.... they played ROUGH but it was play, not violent. (like he's done with male dog next door, coming home with blood)
In the beginning, I was prepared to take him to the pound knowing that he'd be put down. As I've gotten to know him I've come to believe that he's just terribly socialized. He's a VERY smart dog... and his only real desire is to play, play, play, play, play and play more.....then start over and do it again. Has boundless energy.
Still don't trust him in house (not 100% that he's fully house trained) AND his endless getting into things.... so he's lived most of the (mild) winter in our foyer, then on the large deck. Once weather breaks, we've got a fenced in area where he can run but for his ability, it's still restrictive. He needs a good 5-mile hard run to burn some energy off, our fenced in area isn't really big enough for his capabilities. The FARM however, is......but we can't/don't trust him to be free like all the other dogs. (he will actively go next door LOOKING for the male dog to start a fight......he has gone to the NEXT house over and aggressively jumped onto their Husky who's about twice his age BUT she (interesting that he's jumping on a female) anyway she's probably 15 years old so can't defend herself)
So when Wife & I are with him alone, he is a fantastically fun, attentive dog.
Bring a visitor over (mail person, UPS, neighbor, family member) and he goes into red zone ballistic.... but he's now able to deal with brother in law who wrestled with him.
I can't have everyone who might visit first have to wrestle my dog to prove their dominance over him.
I'm not a dog trainer, we got him when he was probably around 2-years old (just a guess, maybe 3-4 but no more) Point being he's ingrained some bad habits that we need to figure out.
Something has to give..... I have a broken wrist thanks to him (I'll spare the story). He's strong enough to pull the wife over if she walks him. Heck, he's strong enough to pull ME over if I'm not ready for his actions.... so something has to give. Rather not take him to the pound because the "good Rufas" is SUCH a fun, attentive loving dog...... but when 'Bad Rufas" shows up..... I'm almost willing to pull the trigger myself.
Any thoughts on how to "break" him from these ugly habits???
Do some research into the proper use of a prong collar. Long story shortened: My wife and I are long time dog owners, she is a vet tech. Several years ago we adopted a largish mixed breed we named "Boone."
Second day home he broke her wrist: collar wrapped around wrist, not paying attention, he takes off. He was pretty much uncontrollable on a leash.
I took him and her into our basement, fitted the prong collar correctly, attached the leash, took a few steps and "popped" the collar with force. He yiped, and settled down.
For the next week when we took our daily walk I put the prong on him and had to use nothing more than finger pressure on the leash to correct him as to his proper location while walking, which is at or behind my left ankle.
He is now the best trained dog I've ever had, for me. My wife he doesn't listen to, but dogs are pack animals, and respect is earned. If you are consistent and don't allow your set of rules to be broken most dogs will get in line. If you are weak and allow them to do what they want they will take charge.
An e-collar, properly used, can curb bad habits from a distance. I always accompany corrections with the word "NOPE" so the dog knows that whatever it is doing at that moment is unwanted behavior. I broke the previously mentioned dog from a pesky habit he had of running away with this technique/tool.
Basic leash training, for the dogs we adopt, is mostly the same. We walk as a pack every morning, same basic route, and during the walk I frequently stop, giving the command "hold up." Command to "sit," then "heel." I do this probably 30 times a walk, over and over, with the leash attached. After a week or so the dog usually catches on and the leash can be removed. I walk 3 dogs every morning, through our woods, and can keep control over all three with voice commands, so I guess my methods work, at least for me.
This short video mirrors what my results were after introducing the prong collar to Boone. Not me or my dog, but you'll get the idea.

I would not suggest pinning the dog and attempting to assert dominance. That can go very wrong in a number of ways. Use of a prong and e-collar is much safer.
