He barks all the time and can be aggresive to people he doesnt know, particularly men, i hav read a few times it helps to have a playmate for them, is this true? i dont want to make him any worse or end up with two badly behaved dogs!! He was well socialised when we first got him, attened puppy classes and we recently had a behaviorist out to see him! Can anyone help me???
Yes, i'm afraid your dog has become a "teenager"! Most dogs go through a difficult stage when they reach 8-10 months old. They suddenly seem to turn into yobs! I think if the behaviourist you saw is worth his/her salt they should have told you that this may happen and how to deal with it. Definately get him castrated if he's not already done. It's not a quick fix and does take a little time to take effect but he will be more manageable if he is neutered.
Also, get him to some good dog training classes, as someone else suggested. Look on the apdt website to find classes near you.
In the meantime, try not to get too cross with him over his behaviour, i know it's hard, but this will only make things worse. Stay calm and in control, and be consistant. If you don't want him on the furniture, stick to that, don't ever give in or you'll be sending him mixed signals. He needs to know the rules and boundries, now more than ever!
Good luck

If I was you I would continue seeing the behaviourist and obedience classes. It could also be the fact that he is becoming sexually mature and his testosterone levels can make him more territorial and aggressive to people , especially men as he will want to show his dominance. If he doesn't show any signs of calming down another option would be to have him fixed. I wouldn't get him a companion as it could make matters a lot worse regarding his dominance and you could end up with more problems.

Take him to a GOOD training class where you can learn how to train him properly:

Get another dog now and you'll end up with 2 badly behaved dogs.

Unfortunately dogs are rather like children,they go through this period when they know it all and the parents (read owner) is someone to take issue with all the time.Your young jack russell is going through the canine equivalent of puberty.He is also having designs on being top dog which accounts for his aggressive nature towards everyone else,particularly males, as he sees them as rivals in his ascent to the top.He requires plenty of exercise to take his mind of boredom and a firm hand in controlling him (no I don't mean beating him !!).You may also consider castration which would remove some of the alpha male tendencies bearing in mind that the breed does not lend itself particular well to discipline anyway.Have two ?You may end up with double trouble and as for training classes save your money and do it yourself the reward is a lot more satisfying

It unfortunately just takes time and patience….Jack's are known for being one owner- one animal in the family kind of dogs….Keep going with the training….how about 1 on 1 classes to un-learn the problems…..lots of love when he does the right thing….I wouldn't get another dog…I had a jack and another dog and the other one suffered because the jack wouldn't let her near me….

You have a dominant dog that thinks his job is to protect -you-
You need to teach him that he doesn't need to do that.
Training classes is the way to go. It socializes the dog and it learns that you are the boss; remember to continue the training once the classes finish.
Don't get a second dog until the first one is behaving well.
