Aggressive dachshund

[TurqoiseJasper]

Long story....I have 2 dachshunds,3 sand 4 years, one has recently become very aggressive.
Completely vet check, no pain triggers. Behaviorist no help really.
After much discussion we have decided to neuter, very much aware that aggression will either improve, stay at the same level or increase. Euthanasia _will be the last option.
He's been on medication the last 10 days or so, Reconcile, which is the same as Prozac I believe.

He has bitten me twice already.
So the op was Tuesday, cone on.
He attempted to get on the sofa and I was behind him, encouraging him with my tone of voice. He turned and went feral, launched himself at me and bit.

Thank god my daughter grabbed the lead(he's on a long line at all times) and in the resulting kerfuffle the cone has come off.

Not a bloody hope of getting it back on. This really is his last chance I'm hoping that testosterone levels drop off fairly quickly, if not I don't know what I'll do, well yes I do I know what will have to be done. I'm upstairs in my room crying now.

I can only hope that he doesn't try and rip his stitches out in the night, and it'll be back to the vet in the morning I suppose to see if they can get one on him. Don't really know why I've posted this I'm just really upset, yet again.

Being on pain relief does not rule out your dog being in pain. A pain trial would look at diferent combinations and mix of pain relief drugs.

No way would I consider putting to sleep until I had spoken to a qualified behaviourist who working with the vet had looked in detail at a med review.

Also pretty odd to have put onto a new medication and then castrated so soon afterwards. Any changes will be hard to know what made a difference. Not somethng a qualified or experienced vet in behaviour would advise.

You need to get qualified advice to move forward. This will be a committment.

There are so many questions. If the dog has only recently turned aggressive there will some change in the dogs physical health or environment. Dogs dont suddenly become aggressive for no reason

Yes, 100%.

The vet doesn't seem to have much of a clue - they won't do a pain trial, but think it's a good idea to try a new behavioural medication and castration in the space of a week?

This dog has been let down, sadly.

Oh and also, I’d forgotten because it’s not a side effect my dog had, but reconcile can cause aggression to worsen before it kicks in properly.

I’m also fairly surprised that he was given it then castrated so closely.
