My puppy's leg surgery pins stick out. Is this normal or safe?

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach! It is normal for pins to be placed so that they stick out the other cortex (side) of the bone, as this ensures they have a good hold on the fracture fragments to prevent any movement of the fragments. As long as Toby does not develop an infection in his bone around any of the pins, and he is not exhibiting any discomfort from them, he will likely be able to have the pins in for the rest of his life. If you notice that the pins seem to be protruding more than usual, or if Toby is lame/painful on the affected leg, it is possible the pin(s) could have migrated inappropriately and/or could have become infected. This would require a visit to your veterinarian for an exam and repeat x-rays, and potentially surgery to remove the pins. I hope this helps :)
