we got our minpin a week ago and she doesn't want to eat. I think she has a cold. but I am really concerned. I know she was used to fancy dog food. but We are trying to get her to eat normal stuff, we have even feed table food.
How old is the dog? Did the previous owner send some of the food she was on there with you? It is best, if you are going to change foods, to do it slowly. Mix her original brand with just a bit of the new and gradually decrease the original brand and increase the new brand. This way she is less likely to have any intestinal upset and also to help her slowly get used to what you plan to feed.
Have you had her vet checked since you got her? You may want to not only get a small bag of the original food, but also pick up some canned dog food and try mixing some of that into the dry food to entice her to eat. For most dogs it will work.
It is not unusual for dogs to go off their food for a short time when they are moved into a new enviroment. Is she at least drinking water?
Life isn't about waiting for the storm to pass. It is about learning to dance in the rain.
