came home from work anbd saw this and its not eating either, but seems to have its mouth full of food but hasnt ate since yesterday. there is also a pit where the it is hanging out that wasnt there yesterday either. there is a gold lab in there and a yellow lab. the gold lab has been chaseing the yellow aton in the past few days and will at times go up to the lab and have what i can only describe as a seize in front of it and then swims all around the yellow and just keeps repeating, the behavior has been goin on for about a week now. any thoughts?
