Why does my dog keep rubbing her nose off the floor when she eats?

What he's doing is probably instinctively trying to cover his food. Some dogs exhibit this behavior, which is perfectly normal. If you put down a paper towel, he may try to use that to cover his food.

She is training you. Do not allow her to do that. Speaking to her at all or standing there while she is eating is giving her positive feedback for a negative behavior. The tendency to hide food and belongings relates to natural instincts of attempting to buy food to "save" for later. First, slightly reduce the amount of food you give your dog. Try to determine the exact amount that satisfies her hunger. Feeding more frequent, smaller meals would be best if possible. Ignore the behavior when your dog is doing it (again, you are giving positive feedback). Any attention to the food dish or her behavior is encouraging her to seek your attention. Put the food down for 10 minutes and then walk out of the room (not saying anything or looking at her). If after 10 minutes she doesn't eat, pick up the food and repeat this again at a later time. Eventually she should learn to eat when the bowl is placed down.

It could be that Uno is moving the bowl to a place that is more comfortable for him to eat, he could be moving it to find a food odor he likes, or he might be moving the bowl so his left side isn't by a wall. Research has found that dogs have a dominant side based on gender, and male dogs tend to favor their left paw. Uno could be moving the bowl to that his left side isn't next to the wall. This is a common behavior in dogs to move their food with their nose before eating, and I wouldn't worry about it :-)

It's a weird behavior, huh? I am not sure why they do it, but many dogs will do this. Sometimes it is that they are looking for a piece that they prefer to eat, they don't like the food, maybe they don't like the bowl the food is in, or they think they will save it for later. Some dogs do this all the time and other only sometimes.

She may have been exposed to something that is making her itchy, a new cleaner in your house or something like that. I suggest giving her a bath with cool water and a mild dog shampoo, making sure to rinse her very thoroughly. If this doesn't help or if she starts rubbing again, I would get her in to see your vet to determine wi there is something else causing her discomfort.

Some dogs stop eating from a bowl and it's fine as long as you are fine with it, feeding directly on the floor would be the preferred alternative method, make sure you clean that floor area after each meal. If you would like to try the bowl again, change the type of bowl and it's size as well, those changes might work.

Some dogs always do this and some do it because they don't want it or they have some anxiety. Does she eventually eat it? If so then she likely just saving it for later. Does she only do it when it is storming or other times when she is anxious? If so this is likely anxiety. Does she never go back to eat it and she won't eat it out of her bowl either, then she may not like that food and is wanting something different. I hope this helps!
