Answer:
My dog baby did the same thing we thought it might be her old age or some thing until we noticed my dog diamond was doing the something and that they had flea they where allergic to them they where getting thinner because they where becoming emaciate by the fleas so we ended up giving them a bath every 2-3 days and treating the house once or twice a week and vacuuming everyday and we helped them gain their weight slowly by giving them butterd rice mixed in with their regular food along with some type of meat baby would get the bumps because she was allergic to the fleas they are both back to normal and are happy as can be
Baby has some bumps on her that has been there for 1-2 years but those are common among older dogs
I would still sagest taking him to the vet to make sure it isn't something more serious but my dog baby was having trouble with her back legs and it was because that was where most of the fleas where feeding on her back half her legs are back to normal and the only thing that is wrong with her is because of old age we have had her scene i was around 3 or 5 i am now fifteen 4 days away from 16 so she's probably around 70 years old in dog years
baby is in the first picture and Diamond is in the second
