I'm really worried about the big dog. She's not limping anymore, but now she's not eating or pooing. She won't even take a dog treat cookie. I hope she's not going to die soon. She's almost 12 years old and that's old for a large breed dog like a Malamute, but still, I don't want to lose her. I decided if she doesn't eat by tomorrow, I'll buy her some soft food to see if it is the fact that maybe she can't chew. *sigh*
