My dog is 13 yrs old.Since yesterday he just lays around,won't eat or drink.He is a pitbull.He did go out this morning and pee then came in and has been laying ever since.He shakes a little too.His eyes look very tired.Could he be dying of old age? Thanks for any help.

What does your vet have to say about it? He might be sick or hurt if it is not his age. When my dog is not feeling well she lays around more than usual and is not as playful outside.

Could have arthritis.. talk to the vet..

It's not a good sign that he's not eating or drinking, 13 years is old for a Rott. Im sorry about you're dog... I see pets as family members and it's so hard to lose one.. My prayers are with you and keep us updated.. and take him to the vet..
