"Petit chien à bélière" means "Small dog with a carrying handle". It's a type of decorative object that was popular in France a long time ago.
Imagine a tiny dog that isn't real, it's just a sculpture. This sculpture would be made out of fancy materials like porcelain or gold. It would be very pretty, and people would put it on a shelf or a table to look at.
But the special thing about this little dog is that it has a "bélière", which is a fancy word for a handle. The handle is usually made out of a different material than the dog itself, like a piece of metal or rope.
Why would you need a handle on a dog sculpture? Well, think about it like a purse or a backpack. Sometimes people want to carry things around with them, but they don't want to just hold them in their hands. So they use a bag or a backpack to carry things on their back or on their shoulder. The petit chien à bélière is like a purse, but for a small decoration. You can carry it around with you if you want to show it off to your friends or bring it to different rooms in your house.
Overall, the petit chien à bélière is just a fancy decoration that people used to have fun with a long time ago. It's not really used anymore, but it's still interesting to learn about!"
