Right I may be an experienced dog owner but this one has me! We have black lab just over a year old, and a choccie lab who is nine. They are the best of friends, sleep together, play together, and have always eaten together. Well trained and well behaved, taught food manners from early age. Last few days though the black lab won't eat, she is not at all unwell. I have always made both dogs sit and give eye contact before food goes down, and they then eat when commanded. This routine has not changed. Normally I have fed them side by side, have tried feeding one ikn the kitchen and one in hall, at smawe time. Black lab won't eat at all. Have tried feeding at different times, with choccie outside in case it is a dominance issue, black lab won't eat. I have sat with her and hand fed her out of the bowl and she did eat most of that, then put a treat in the bowl on top of rfemaining food, and she carefully removed the treat from the bowl and ate it, but didn't touch the remaining food. She is a n ervous dog, eager to please, who likes lots of positive reinforcement, and routines which I always stick to. What do you think.....what is the best way to break this silly behaviour?
