My dog stopped eating milk bones all of a sudden, anyone know why this might be?

I have a 6 year old Labrador retriever who loved milk bones (cookies as we call them) and all of a sudden he does not eat them any more. He pushes the cookie around seeming scared of it then starts running around like crazy like he is excited. Any ideas?

oh, this happened to my dog, also. My sheltie LOVED milkbones then one day he didn't really care for them, your dog is probably just sick of them. try getting some new treats then eventually you can go back to milkbones.
I also have to change up the treats I give my dogs. My boxer mix will eat anything put in front of her but my beagle will like a particular bone or treat for a few weeks and all of a sudden she just loses interest in it.My dog stopped eating milk bones all of a sudden, anyone know why this might be?
he might be sick of them like you eat things too much you start to get sick of it.
