Hello. Please can anyone advise. We have a 2yr old, neutered, dog Parson terrier. He is agression with some other dogs and poor to recall when it matters. We have socialised him since a puppy. He lives with another dog his age. We have taken him through 2 training regimes without much success.
We are aware he may just need more stimulation than we can offer him. I am concerned about rehoming for obvious reasons
I need any experienced advice and help please specific to the breed.
He is fit, healthy, loving and keen to please. He may just be in the wrong home or we are doing something we can change
Many thanks

Being aggressive with other dogs is a terrier trait so is selective deafness if what they are doing is more interesting that what you may have on offer. As you are talking of thinking about re-homing I guess this problem is severe and it is the aggression that is problem you are finding most difficult.

Does he get on with his fellow kennel mate? Did you have them both as puppies? What made you decide to castrate? Yes, I am nosy but that is not the reason I asked but rather to better understand your problem or rather that of the dog.

Can you give details about the previous training regimes?  Any particular dogs he's aggressive with?

What age was he neutered?

Hi
Thank you. Neutered at 6 months. Training has been puppy class for socialising and basic training then we have had 1:1 work using whistle and calling for recall with a lunge lead - standing on the lead and calling at the same time to associate dead-stop with our command. Works until he sees something more enticing! Walking to heel is a disaster. Always wants to be where we are going not interested in the journey. Tried heel command and treat and also bell on lead association theory. Improved a little. Stays on command very well.
First sign of aggression was with a 12wk old when he was about 9months old, we were all in a local park with other dogs and pups he knew. This pup was new to the group. Snapped at the side of the pup's head. Usual place he snaps now. Seems less interested with pup's now, but bouncy dogs he has a snap at. Has had a pup by the fur of his neck once without drawing blood but horrible.  Never has caused any bleeding. Rarely barks at anything.
It took us about a year for him to wag his tail. Always quiet and reserved. Now much happier and VERY keen to do the right thing so all this is very distressing to him as well as us.

When did you get the other dog, how old was the one you are having trouble with at the time and how far had your training with him got.

Castration so young may well be the problem but that is something that can't be undone so we need to try and sort the problem, from what you say he does sound unsure of himself. What other sort of training have you tried apart from the whistle have you tried toy or food reward?

calling for recall with a lunge lead - standing on the lead and calling at the same time to associate dead-stop with our command.

Surely that is teaching him that being called means something unpleasant happens (potentially dangerous to the neck too), not something nice. Being called should mean everything nice in the world is about to happen -treats, toys, cuddles, praise, play etc etc.

Hi
Both were 10 weeks when brought home. Both on same day.
They are treated to death! Loads of genuine praise. Tried balls, sticks, toys - all to some effect but treats are the key. They are loved and praised when good. Not praised when bad but quickly reminded that a good thing is praised

Do you spend time training and walking each one on its own and have you done so since they were first with you?
