Hey Maple, you might try liquid children's aspirin if you can find a reliable dosage. It is sweetened liquid usually, and easy to hide in food. When my rats need pain killers, they readily lick it up straight from the syringe. Crushed tablets can also be hidden pretty easily though, and then are easy to digest. Nella has a good point though, if the pain is there but not too great, it can help keep them from causing further injury. She's back to her old self...took her a little less than a week til she was springing around again (at mach ten). The bandage really helped stop her from licking at her foot, but if you have a really mouthy dog, you'll want to make sure they don't eat it!
