My newborn puppy has a deformed leg that smells bad. Is it infected?

Updated on September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | 4 days old | 1lb

I have a 4 day old pup with deformed leg. It is very flimsy like it has no bone and pup is dragging it around. The thigh/hip area is much larger than the other side. The deformed limb has developed a unpleasant smell. It looks like the cord was wrapped around it. Mother treats pup the same as other two and pup seems to be healthy. Should I be concerned with the smell, could something be going on in the leg thats not visiable. Is pup to small to have leg removed even if it is decaying.

Poor little Princess! You will need to take her into a vet as soon as possible to get this checked out. If there is a smell, I would be concerned about an infection. She is too young to have this removed surgically, but any infection has to be treated now. When she is older, the vet can amputate the leg if needed. Please take her into a vet immediately. Best of luck.
