pin in leg

i just got this min pin and he is aboput 3 years old. he is very small at 6 lbs. he was apparently hit by a car in nov. and had a pin put in? does this have to be removed or can it saty in?

Ask the vet, but usually, if a pin is installed in a leg, whether in a person or a dog, it's a permanent addition to the bone that stays there, because the bone needs help to stay together & support weight. It's done in cases of very severe damage to the bone.
   
Do you have the MinPin's previous vet records? Get them if you can & give them to the vet. He'll need to know about the operation.

i spole to the vet that did his surgery but i do not like that vet, they are one of those very high priced, anything for money places. i want to take him to our vet to find out for sure. of course, the first vet said that it has to come out.
   
i am just trying to find out how quick this has to be done, if it does at all
