A dog presented for limping on its front leg. It had been doing so for one week. As an aside, please do not wait one week to seek medical attention when your dog is limping! The area below the elbow was swollen and extremely painful. The lightest touch caused the dog to scream. The dog is fully vaccinated, on preventative for heartworms, fleas and ticks. Once the dog was anesthetized, two sharp foreign bodies were felt under the skin in the area below the elbow. Look at the picture and name the foreign body.
Diagnosis: Cactus Thorns
Close inspection of the image reveals a long thorn in the jaws of the forceps. If you look on the left side, you will see another incision where the other thorn was removed. Below is a close-up of the thorns. Ouch!
