That's what I think too. Pugs are prone to obesity and JRTs aren't. JRTs in general have a high metabolism therefore wouldn't be as likely to become obese.

I too recommend no longer free feeding. Offer them their food (each in their own dish) and take up anything that isn't eaten after 10-15 minutes. Green beans with Sylvia's food is a great idea. I would also go with a reduced calorie diet for her. I'd keep the other two on their regular food as long as you are happy with it.
