Wing trim? for safety?

[Anansi]

It has nothing to do with good owners or lazy owners, it has to do with the unpredictability of animals and the fact dogs are natural predators and parrots are natural prey animals.

Exactly! We must never lose sight of this. The natural relationship between a dog and a parrot would be predator to prey. And a dog cannot be expected to do otherwise than to chase down and kill its perceived prey at any opportunity without extensive training and conditioning.

Your 4 dogs are no exception. (At least one of which - the golden retriever - has that response practically hard-wired into its DNA.) I'm not saying that it cannot be done. I've actually seen it done very successfully at (Jersey) Wendy's house. But make no mistake. What is being done is the sublimation of the natural predator drive. As such, their behavior can never be taken for granted. And a lot of conditioning has to go into it.

So if your reasoning for either clipping or leaving your bird flighted is based upon which leaves them more vulnerable to your as-yet-untrained dogs, I think you may be viewing the entire situation in the wrong light. I think they have to be kept largely separate until their prey-drive can at least be somewhat subdued. You just cannot rely on a parrot's ability to take itself out of danger. As Walt pointed out, being indoors places them at far too much of a disadvantage. The responsibility has to be yours.

And this is true even after your dogs' conditioning has reached an acceptable level. You can never completely trust a predator with a prey animal. You just never know. The prey-drive can be sublimated, but not eliminated.

Respect the drive.

So whether or not you clip is up to you. I personally prefer not to, but I know there are instances where it might be necessary. And other people's preferences differ. Personal choice. I can respect that. I just hope you don't base the decision on what will enable your parrot to survive your dogs. Flighted or clipped, that's a losing proposition.
