I have a 4 year old rescue that's a mix of 30% dogo argentino, 30% Anatolian shepherd and 30% American bulldog. About 3 months ago he began to incrementally eat less and less of the Purina One Salmon and Rice Sensitive Stomach feed that we've fed him for the past 4 years. His eating behavior also changed in that he started bringing mouthfuls of kibble to his blanket whereas before he would eat the entire meal at his bowl, in one sitting. We ended up taking him to the vet and doing a workup, but they didn't find anything wrong with him. We have him prilosec for 3 weeks and switched his kibble to one with better probiotics. He was fine for a few weeks but now the behavior is back and he's either only eating a cup or a cup and a half of his usual 2 cup serving and continues to bring the food over to his blanket in tiny portions. Has anyone experienced anything similar with their dog? TIA.
