Seroma - Drain OR not My puppy was bite by another dog about 10 days ago. The wound was not big and heal very fast. But right now I found there is a seroma on his neck, "tennis ball" size. But he is normal as usual, full of energy, eat good, no painful, no fever. I took him to the vet, the doctor suggest me to do the surgery and drain the seroma. The cost is about US$1200.00. Should I do it or not？ As I checked on line, normally the body could slowly reabsorb the fluid of the seroma. Thanks in advance!!!!!!
