Have you felt all over the leg to try and find a sore spot?
How much does he weigh?
Is he on any other medication?
His dose would depend on his weight.
Ice therapy, for 20 minute intervals, is best for the first 48 hours after the onset of an injury.
He can have 200 mg of aspirin total. You can repeat the dose every 12 hours. It is best to give it with food.
Dogs can not have ibuprofen, tylenol, or anything else as they can not metabolize it.
Ice is best in the first 48 hours. It will reduce any swelling and inflammation. On myself, I like the heating pad but I know I am suppose to use ice. So, you could alternate ice and heat therapy. They have actually found this alternating confuses muscle spasms which makes them relax.
