While not strictly a bike, it is bike adjacent. I am trying to convert an old schwinn kids bike trailer into a dog trailer.

I am hoping to be able to grease the wheels. It looks like there is a ring I need to remove.

A sealed bearing, which can’t be greased or serviced

Yes they can. You can remove the seal, clean and re-grease it and put the seal back on. I've done this who knows how many times. It's not as easy/effective as with cup and cone bearings but it can definitely be done.

However, it's still recommended to remove it for easier cleaning so might as well replace while at it.

Yep. I'm using dentist's pick for removing the dust covers, it's a nice stiff and thin tool for this job
