Has anyone tried it on their dog? I'm interested in the implant you can have, which mimics having your dog neutered. I'm particularly interested in, if it calms a dog down. I have 4 Bulldogs and the fighting is wearing me down, 3 girls and 1 boy and he just loves a good scrap but it goes too far and I'm really worried that they will get badly injured. This is my last hope before we seriously have to consider rehoming him. Just wondering if anyone has experience of it, but I will be talking to my vet to get his opinion and advice too.

I don't know anything about it, but here are some people who seems to have had it done.

Never consider castration for behavioral reasons without getting an expert assessment first from a qualified dog behaviorist (you can find these from the APBC, COAPE and UKRCB). I emphasize qualified as there are many glammed up ten-a-penny trainers out there who also call themselves "behaviorist" - without any of the degree-level studies that should go with it.

In short, if his aggression is motivated by testosterone fueled confidence or sexual motivations, it can help. If it's motivated through fear or space/resource/object guarding, you can make things far worse.

There is a very good read here on the behavioral pro's and con's of castration:

I wouldn't put too much emphasis on a vets opinion, they are qualified in matters of the body, not the mind, and many push neutering as a nice little earner, and on ethical grounds of unwanted mating's. They may be able to recommend a local behaviorist though.

Personally I think the jury is still out on chemical castration, and it's a risk I wouldn't take. There's a success story here:

And an awful story here that ended up in the dog being PTS

Why take the chance? Surgical castration is such a simple and routine procedure, and also removes any future risk of testicular cancer.

I would be more concerned about impact of the chemicals rather than surgical removal of the fluffy bits.

Depends on the dog and the issue IMO

Our older dog is not recommended to be neutered as he has joint issues. We used the implant when he was adolescent to stop his manic humping, but training worked eventually.

Those 'fluffy bits' do more than make babies!!
