My parents have a 4 year old english springer spaniel entire male, who they got as a 2 year old from his breeder. His breeder had showed him (Liam) with some success, but he was fighting with another of the breeders dogs (again an entire male) so Liam was re-homed. I'm not sure if it was Liam or the other boy that was picking the fights, and I think they decided Liam should go as the other dog was doing better in the show ring.

Liam settled in well with my parents, he's a happy dog who seems to have adjusted well from living in a pack of dogs to living on his own with my mum and dad. He still gets to spend time with other dogs though out on walks, my parents have friends in the area with dogs that he gets to play with on walks.

However, earlier this summer he was attacked by a large dog, and since then he's been a bit 'funny' with some other dogs. He's been aggressive towards large male dogs, snarling and if he's given a chance he'll attack. We think it's driven by fear, as he's picking on the larger, scarier dogs, but he's now shown aggression towards small dogs too. As far as my parents are aware, it's only male dogs he's going for.

He remains a good dog around people, and still gets on with male dogs he knows. It's just strange male dogs he has a problem with, but there's quite a few of those around! Interestingly, he was good in the show ring when they showed him recently - mum made sure he didn't touch noses with other dogs and he behaved himself impeccably, but out of the ring it was a different story!

I'm not entirely sure how they discipline him when he attacks other dogs (other than pull him away, I'm sure) as I haven't seen it happen. Also, I'm not sure if he knows the word 'no' though, because he is generally good, and my parents weren't the people who laid down the boundaries with him as a pup. They did take him to dog training classes for a while when they first had him, where he learnt to sit, lie down, stay & recall - he was never the most obedient and was easily distracted, but he did learn. And like I say, he was always good with all the dogs at these classes, but this was before he'd been attacked.

Does anyone have any advice? Mum and dad are considering having him castrated and will definitely do this if it will cure his agression towards other dogs, but they don't want to do it if it won't improve his behaviour with other dogs, as their previous dogs have always become much more hungry and put on weight after they've been castrated. They've tried a halti on him so they have more control (he's normally good and doesn't pull on the lead, but I think it's a different story when he's got a target lined up!) but he didn't like and tried to get off. I'm fairly sure if they perservered he'd get used to it, but it's still not curing his aggressive tendancies. They're going to try a muzzle on him too, but I don't think they want that to be their long-term solution. Any advice would be greatly appreciated - they've never had any experience of owing an aggressive dog before, so are at a bit of a loss as to how to put a stop to his bad behaviour.

Having him neutered if you are not going to breed from him is a good start and for his health, it will not cure the aggression nor make him fat.

A good behaviourist should be able to help him and and your parents would benefit also. As he has been attacked by a larger dog he is rightly fearful so before it escalates see a behaviourist.. Your vet should be able to recommend one but check that they practice positive reinforcement. I had very good results with the same problem using clicking treating.
 
I had a very similar problem caused by one of mine being attacked by another dog, and her fear aggression towards other dogs passed itself on to 2 of the others so I ended up with 3 aggresive dogs to control. I got a behaviourist in and got the dog they were the most aggressive with and it's owner to work with us all. She explained that I needed to take control, that my dog could be scared but needed to know that I was in charge and she was not to react. She brought a small plastic bottle with half a dozen stones in and told me I had to shake it right in her ear as soon as there was any sign that she was going to react, shout NO very loudly but give her no praise when she calmed (I can't for the life of me remember why this is but it made sense at the time!) Try and involve people that have dogs your dog doesn't like and walk them past each other as many time as you can.

Over time (it took about 3 weeks) when they all stopped the aggression I was to allow the dogs to meet on lead, keep myself very calm and make soothing noises and say things that the dogs reacted well to like 'there see nice dogs etc' but shake the bottle if there was any grumbling. Allow them to sniff but then walk away without taking it further. I've tried similar things before so I wasn't expecting miracles but it did work and my dogs are much better.

When he fears something (in this case large dogs) he goes into attack mode - I'll get in there before they do. If he were human he would have a combination of hypnotherapy, cognitive behaviour therapy and possibly anti-anxiety medication. He needs to learn that large dogs are not something to fear. I would get him to socialise with as many different sociable large dogs as I possibly could. Ring around your local training clubs and ask if they can assist.
Your parents also need to display positive behaviour around large dogs and not start to tense up. I wouldn't be letting him off the lead at the moment and as long as your parents can control him on the lead, there is no need for muzzle.
 
My labrador is the exact same, we got him as a 8 week puppy, he was the most friendliest dog ever until he got attacked, not once but twice, the second time was a big german shepherd who pinned my dog down and attcked him. Since then my dog will attack any other make dog that shows him any signs of wareiness. (if a male dog comes over tail wagging and wanting to play, my dog will be wary but then will play, if a dog comes over and is wasy of him he doenst even give them a chance he goes straight in for the attack. (This again is just male dogs he is fine with female dogs). He is also entire. I have spoken to my vet about him and although they said neutering may help it obviously isnt a guarentee. Im also at my wits end with him as when we go out im frightened of letting him off a lead just in case there is another dog about that he will attack. Maybe re training is the answer ??

Please tell me you muzzle your dog when you take him out ?
 
As I am a responsible owner I do muzzle my dog when he goes out as I wouldnt want him to attack another dog while were out, just a pity cant be said for all dog owners as my dog wouldnt have been attacked and wouldnt have the temprament he has now if that was the case!!
