My black lab is sick

Question
I have a 13 year old black lab and last night when I got home she just laid on her side and was pushing like she wanted to give birth. Shes fixed and her belly is really hard. Today when we got up she walked a little ways and laid back down.Is it her time?

Answer
Please do not waste any time in getting your dog to a vet.  Just because she is old does not mean that she is beyond help.  It would be wise to find out what's wrong and if treatable, take care of it.  If she is indeed sick, then your vet can give you options for what's next.
