So I feed both my dogs about 10am every morning. My hubby's dog I feed Blue Buffalo. My dog I have to feed her Science Diet Sensitive Skin. She has some food allergies so vet wanted me to feed her that to see if it worked and it did. She used to be fed Blue Buffalo too but she was chewing at herself and causing raw spots above her tail. Once we switched, her coat started to shine and hair came back. She has been fed Science Diet for going on 2 years now. She loves it! However, lately she will eat the bowl down to about half, pick the bowl up in her mouth, dig a hole, flip the bowl of food into the hole and burry it! After I got tired of doing that, I started tying the bowl to the fence so she couldn't carry it off. Then when I went out, the bowl would be full of dirt from her obviously scooping dirt up in her mouth and covering the food. Why is she doing this? She isn't sick or acting any different besides this out of the blue behavior. This has been going on for 2 weeks now and the expensive food is going down the toilet. Both dogs have separate kennels outside they get fed in and neither dog ever gets to go into the others kennel.
