The vet told me my dog looked like she ate something like a sock but they could perform surgery so to go to another vet. Went to the emergency hospital and was told my dogs BUC and creatine levels were at 5.7 and 170 and she was totally playful before lost weight out of no where. they said her kidneys never formed properly. i don’t want my dog in pain but i’m not saying good by to my five month old puppy without a good reason.
