Hi Vikki,
Growing up I had a Springer and I also have one now-and they would both eat all day if they could-dog food, cat food, fish food, rabbit food-they're not fussy, my current male in particular! What food are you currently feeding her on? I ask as I found a slight improvement in my dog when I changed him onto a more "wholesome" food, i.e. I now feed a combination of Burns & Naturediet which seems to fill him up a bit more and for a bit longer. However, in my experience Springers are intrinsically a greedy, food-orientated breed so I wouldn't worry that her behaviour is abnormal! :)
