Overweight dogs. Health

I saw her very briefly on tuesday and i could pinch skin all over her body, but as the fat has gone we have found lots of lumps so a trip to vet was had. He thinks they are just fatty tumors but untill she loses more weight he cant do much so we bought her some of the hills science plan diet food and are going on advise from our own vet about how much to feed and how much to walk. He recommended we increased her excercise as getting the weight of is more important at this time. He has sent a report over to her own vet as she is going home tomorrow. If the weight her owner gave us is correct she lost 10.7 kg in her 3 week stay. Better than nothing ild say. Skin around her neck and chest had gone quite baggy but her body was still big enough to make her head look out of proportion.
