Question
I HAVE A RAT TERRIER HE IS 17 YRS OLD HE HAS STARTED PEEING IN MY BED THEN GOES OUTSIDE TO PEE AGAIN
HE JUST STARTED THIS A COUPLE DAYS AGO
IS THERE SOMETHING WRONG WITH HIM

Answer
Yes you should take him to a vet to get him checked.

He seems to be at an old age and this usually happens to elderly dogs because they can't control themselves.

Take him to the vet and they will provide some
Prescription medicine for them to heal you dog.
