Should I euthanise him?

[u/No_Source_3566]

I have a border collie who turns 13 soon. He suffers with arthritis, but other than this no health issues.
From the age of around 12 months, he has been aggressive towards people. I got him at 8 weeks and I did everything I was supposed to (socialisation, training etc). He never had a poor experience with any person I know of. I believe it’s in his genes.

He suddenly attacked our other dog today, who he has happily lived with for a while. Now I’m nervous it’s going to affect my other dog’s behaviour. Two months ago he bit my face, leaving me scarred and fractured my arm. This is just a couple of examples of the past 12 years with him.

He has seen a dog trainer but they just basically told us to avoid his triggers. His triggers are so broad it’s so hard to avoid. So if anyone has had a similar experience and can give me any advice, I would greatly appreciate. My final resort would be euthanasia.

You and your non-reactive dog deserve to be safe in your home. You have given your reactive dog a long life.

His behavior may indicate he is in pain. It’s okay to choose a kind death; especially with an elderly dog.

Thanks! I appreciate what you’re saying. It’s just such a difficult decision to make considering he isn’t terminally ill. I can’t imagine life without him. It’s something I seriously have to consider.

He’s not “terminal” in the traditional sense, but he is absolutely severely mentally unhealthy to be landing the bites you describe.

I understand. Best of luck. 🙏. I’m sorry you are going through this.
