My dog has a tendency to eat things he should not, I'm afraid he might have gastrointestinal blockage?

I have an 11-month old corgi, and over the course of several months he has chewed on (and potentially ingested some pieces of) shoes, plush dog toys, rugs, etc. I know it's not healthy for a dog to be chewing on all of these things, but it's impossible for us to be watching him 100% of the time, and we do our best to keep him crated when we are not home and to keep tempting things like shoes out of his reach, but mistakes happen. The more things he chews on, the more I'm worried he might have something blocking his digestive tract, some stuffing from a toy or a bit of synthetic material from the rugs. . . He doesn't seem to have any symptoms of gastrointestinal blockage, and I certainly don't want to take him to the vet if I don't need to, but has anyone else had this problem and worried about it? And should I take him to the vet for x-rays or anything??
