My small dog (about 22lbs) was hit by a car and broke his femur bone. He had surgery Wed. Dec. 5. I brought him home and kept him quiet like the vet advised. Only walking him to go potty. He began swelling above the incistion where the pin was put in. I took him back to the vet and she told me he was over active. So I have been carrying him up and down the stairs when I take him to go potty and even carrying him back into the house after he pottys. He has really not done anything but lay around the house and maybe walks a little from room to room. Now the swelling looks like it is getting bigger. Any thoughts or suggestions would be really helpful.
