We have had roxy (lab/pit rescue) for about two years now and have had several hurdles with her being a picky eater. After some stomach issues she finally settled on a dry dog food that she was always excited to eat, Science Diet Light. A few days ago I brought home a 2 year old german shepherd (work dog) and began the introduction process. Most of it has gone well but the part where we have been clueless is the feeding. To date there is no food aggression from either dog, however Roxy is no longer interested in her food and only wants what the new dog is eating (Science Diet Active). I have tried feeding them at the same time and separately. When I feed the shepherd in his kennel roxy will lay outside his kennel until he is done and will not touch her food. I tried feeding them both a few feet away from each other and neither could focus enough to complete their meal and roxy had zero interest in her food until I dumped her food into his bowl once he was "done". Any suggestions or insight on Roxy's behavior would be greatly appreciated.
