hi, so my dog - 4 year old cavalier king charles spaniel, male, neutered - has been on canidae ALS and lamb/rice formula for several months now. in that time period, he has gone from weighing almost 29 pounds to a solid 23 pounds. He had always been slightly over weight, even though he was slightly large for the breed. he seems great - energetic on walks, bright eyes, healthy appetite, good stool, clean teeth, etc. but i was wondering if should be concerned that he has lost 6 pounds - because he has never lost this much before. previously he had been on natural balance reduced fat diet and the canidae really seems to be working out for him. thank you!
