last night for dinner i fed my 3 month old staffy a can of food that she has never eat before because i ran out of the food that i was previuosly give him. it was called natures gift. he ate more than half of a 380g can and seemed to like it. next morning i went to go see her she was excited but was shakking and seemed wierd and wasnt that energetic as previuos mornings. gave her some pedigree solid food but didnt eat that much and went to school. i came back about 2 hours later and seeing him really weak. always lying down and sleeping. he use to be always running around and jumping but now he just doesnt move around that much. somtimes when i touch him he screams. what is wrong with him?
is it because i fed him the new food to much? or what? im really sad and really feel sorryy for him
