My husband and I have a smooth Collie German Shepherd mix that we adopted when she was seven months old. She is now two years old. On and off she has lost interest in her food but is very alert and very playful and drinks plenty of water. Has anyone else ever had experience with their dog going off their eating schedule and how do you get them back on it? It's been a week to a week and a half that she's been doing this. I feed her 1 1/2cups grain-free kibble in the morning with grain-free wet dog(1/4 cup) food mixed in it with omega-3 supplement. Same thing for her dinner time. Recently I've had to add to it boiled chicken enough to entice her to eat it then she lost interest in that and added cooked brown rice to it and she ate that just fine. I'm not sure if she's just getting finicky or what the deal is.
