Our 8 year old Schnauzer needs some help

Sadie's 7th birthday party

Sadie has started panting quite a bit for the last 4-5 weeks and now she pants when she gets up to go across the room to get to her water fountain. She is fairly lethargic and doesn't move as fast as when she was a puppy. We tend to overfeed her as we really don't have any willpower when it comes to those sad, sad eyes.
I am thinking this could be the start of diabetes or maybe cushing disease. Please, any help will be appreciated as our funds are low because of the economy and we don't know where to take her since her regular vet moved away,
