We had a westie ,she lived untill she was 19,but old age got the better of her,she became deaf and blind and basically just kept sleeping/eating and messing everywhere,so we had to decide to let her go.However...all the time we had her and all our other dogs,we have allways given evening primrose capsules,1,000mg once a day in their food or as a sweety.Holland and Barrett,however......i have to say you should NEVER give a dog aspirin or any other human painkillers.I am speaking from the knowlage of knowing someone who did this and it did alot of harm to the dog.Regards.
