ok so I have a small min-pin mix and all of a sudden he is shivering, constantly licking his lips, wont go outside and go potty, wont eat, and acts like he is afraid of something but there is nothing around to hurt him. he is fine under a blanket but he doesn't look very comfortable when he moves/walks and will only fallow me, yesterday we had to "put down my rat" (we just shot the poor thing to put her out of her misery), could her death and absence be affecting like him like if a human mourning (I was crying a lot). this all started today.
