In practice, people bring all sorts of dogs (or other "regulated things"), of all sorts of sizes, onto the Metro and Buses and RER trains.
I have very rarely seen people with their dog in a basket or carrier for the bus, or travelers holding the animal in their arms (unless they happened to do that all the time anyways).
On occasion a driver may take exception with the size of an animal or a baby stroller; If s/he does, they'll tell you. I happened to see this today actually. A Metro train driver, driving with their door open, told a lady pushing a stroller that she's not allowed to bring that on the train (I assume because it was rush hour). The mother, surprised, asked, "Why?", they discussed a bit, and then she boarded anyways. It wasn't like the Metro driver could stop driving the train to prevent this lady from riding.
On buses, that could be a bit different. But, again, I've seen dogs on buses that are most definitely larger than the "maximum" dimensions they specify on the RATP site. And if you already have tickets purchased for the bus or are using a pass, you can simply enter by the rear door, validate your fare (with the readers/composters there) and avoid any sort of contact with the driver.
As a rule of thumb, the object that one brings on board any type of public transportation shouldn't prevent other riders from also using the service. If your dog was taking the physical space that prevented another human rider from taking the method of transport (due to the volume of people at that point in time), then the dog shouldn't be there. Otherwise, there shouldn't be any issue. Please keep in mind that that's my interpretation of the intent of the rules. The regulations are up to the interpretation of any given "controller".
I hope this answers your question.
