Q: We have a 6-year-old Pyrenees mix who is very well behaved. About a year ago, she started to pick up mouthfuls of her dry dog food and spread it around the kitchen. She started out with just a few pieces and has gradually increased the amount. Of late, when we are gone, she will spread half of her one cup allotment everywhere in the kitchen, including trying to bury it under a rug by the back door, which makes it difficult to open. We have tried leaving it and not giving her more food until she eats what she has spread. She ended up losing about 10 pounds. We tried putting it back in her bowl. She puts it back on the floor. We tried throwing that food away, to let her know that she loses it if she spreads it, but this has not stopped it. Why after five years is she starting it now and how can we stop it?
