Is it a companion dog show? If so, why not, it will be fun. The steward will bring you into the ring, where you line up. Make sure Archie is standing nicely. Some people will "stack" their dogs which is just making sure they are stood correctly. I wouldn't push it too much at this stage. Just make it fun
The judge will then get each handler to bring their dog in front of them to go over them. They check teeth, run their hqnds over and my touch his crown jewels lol. They will then stand back and ask you to move him. It's usually in a triangle but just watch what the others do before you, if you are not first. You stop in front of the judge, she will have a last look and call foe the next handler. You will then join the back of the line.
When the judge has gone over all dogs, you want Archie standing and the judge will look at them all again and call out the winners. If you are one of them, you stand where they are pointing.
It could of course, be slightly different. Just remember to listen to what the judge or steward tells you.
Good luck.
