My Buddy Boy Needs Prayer

My Buddy Boy needs prayer. He's really sick and losing weight all the time. I had him to the vet two weeks ago and got some meds for him but he's not getting better. He is the same age as my little Libby (who past away on Valentine's Day. Both 16 years old. I just  can't stand to think about losing Buddy also. This is not a recent photo of Buddy Boy
