She will eat raw hide treats but just one or two and then if you try and give her dog biscuits she may eat one and then dig the rest in the ground or just set it down and leave it alone. She is about 4 or 5 years old, and I don't know what kind of dog she is. She was given to my family when we moved into a house. She has a long body, like a daschund, but much bigger than one, with short legs and a head that resembles a lab. I'm really worried she may continue this habit, and face sickness.
