My dog takes 2 benedryl, twice daily to help with histamine for allergies and her history of mast cell tumours.
She is getting stiff after having had both her back knees fixed from cruciate surgeries.
Can I give her a plain aspirin a day with the benedryl??

Years ago we gave our first lab l aspirin a day for stiffness from when she was 9 till she died.
It helped her a lot then.
