Is low dose paracetamol safe for dogs?

NO! Dogs are not little humans and do not respond to human medications like people do. Giving a dog human over-the-counter pain medications could kill the dog; I have seen this happen before.

If you dog is in pain, you should ask your veterinarian what you can do for him/her. There are several medications available that are specifically designed for dogs, although they can be expensive. Also, your veterinarian should do a complete physical exam, possibly with bloodwork or other lab tests, to determine what is causing the pain.
