Jack is sick

Jack isn't feeling well today. I'm really worried because he's over 14 years old. I woke up this morning and Jack just had this worried look on his face. He's barely capable of walking on his own power and I had to carry him to the front and back to his bed for him to do his business. Since he is having stomach problems, I'm hoping that's all it is. If it carries on I'll have to take him to the Friendship Animal Hospital later today.
