JRT increasingly aggressive

I’ve also got a roughly 5 year old Jack Russel here, the dog is a complete arsehole. A few years ago he had a fight with one of my patterdales through the kennel bars and basically chewed his nose and half his top jaw off so the poor patt had to be shot. In more recent years he took a dislike to one of my spaniels (a dog) and would latch on to him every time he walked past! Eventually he gave up on him and took a dislike to my bull x lurcher, luckily for this Jack Russel the lurcher is in his senior years, if this was a few years ago he’d of just picked the little tw*t up, given him a good shake and made damn sure he never did it again!!
Said Jack Russel had his nuts off about 18th this ago…made sod all difference!
Only stops 'em breeding always been the same but the vet earns a good few quid ! Is it worth keeping nasty dogs ?
 
Turn the collar up to max then.
I meant to get a collar for a long time, just never got round to it.
Half of it is boredom, he is/was one of my working terriers from my days in hunt service (obviously bolting foxes in to a net to be shot, for the protection of game birds) and now the most he does is kill the odd farm cat!
 
I put in a lot of time with two old terrier men (legends) doing dens and bolting the foxes to the gun and yes some are just plainly friggin` aggressive bastards. I wish a collar could be had in those days.
 
I’ve had white dogs for over 20years,all from the same line ,I’ve some that are good with other dogs an some that are a nightmare with strange dogs,having the balls off will not work on an adult,electric shock will not stop a fired up terrier unless it was to knock it off its feet-paralys it.
mine are never off the lead unless working- problem solved.
 
He had his balls off a couple of year ago following some decidedly perverted behaviour with one of the spaniels (sticky ears…).

In response to some of the posts above, he seems ok with smaller dogs but hates bigger ones. He did get attacked by a pointer a few years ago but there was no spike in aggression to bigger dogs directly after, it seems to have ramped up in the last 6 months.

Looks like the little sod will be confined to lead walks in busier places for safety’s sake.
 
Personally I'd look into taking it to a proper trainer that's knows wot there doing..
Realistically ur going to be walking it 2 times and day fir next 5-7 years on a lead lunging at every dog it passes.
F#ck that, not much fun that.

I would be fairly certain be a cure for it using positive methods, but even if ur going to use negative methods u still need to understand why it does it and wot the trigger is.
 
IMO , the only way you can sort a " proper " terrier is facilitate and guide it into proper work ( while remaining the boss of operations) . You dont really train a terrier , they dont really care so much for praise and treats like your regular Labrador / spaniel etc ( certainly not when there is scrap to be had or agro started ). Man fixed it like that when he got small dogs that actually wanted to go underground to tackle Fox and Badger etc to the death if required, yet that dog weighed in the same weight or less toe to toe underground .
 
Maybe what is happening is that your JRT is maturing into a highly dominant dog that tries to boss other dogs. In which case I would suggest getting together with a pal who has a larger even more dominant dog and allowing the JRT to interact with it in a controlled manner so it can learn submission? Once that submission switch flicks in a dog's brain in my experience they tend to settle down.

what could possibly go wrong ?
 
Unlikely to change whatever you do.
Live with/around it or the alternative.
Took me 5 yrs to get my best mate ever to a point I sort of lived with.
I'd trade days now for days then.
 
Must admit never been a terrier owner althou previous bosses/head keepers were right into them.

A lot will depend on the temperament of the individual JR, not all JR are complete head bangers.
I'd definitely get a 2nd opinion from someone who knows wot their talking about, even pay for it.
iif u want to keep the dog and not happy with the present way it is
 
It appears that many have the idea that working terriers are incorrigible untameable bastards. That is wrong as they are just another dog and as trainable as any with the correct rearing. When they are out of hand its because they have been allowed to be a right **** and the bad behaviour wasn`t shut down from the start.
Two names from 40 years ago, Michael Walsh (91 if still alive)and Alan McNutt (dec) are two of the blokes I learned my terrier trade from. Both of these blokes had an average of 20+ terriers each (yes twenty)for rough cover hunting and doing trees, hollow logs and dens. They were all under control, yes sure there was a lot of pi$$ing, scratching and snarling but they were there to do a job and knew it.
Another bloke JT worked at the Lost Dogs Home and any "likely" looking terrier would be saved from the green needle and brought up to the farm. Straight off a sofa to the wilds of Lancefield and believe or not two of the finest "go to earth" were sofa dogs believe or not.
Whatever their personalities it was all kept in check by blokes that KNEW how to go about it. No wishy washy hand wringing ****ing about was entered into. ALL terriers are trainable except for point one of a percent, they end up in the earth also.
