 [ Symptoms ] i am taking lidocaine patches and would like to know what it does [ Disease ] i am not a vet but i do have 3 dogs and 3 cats so i have a lot of personal experience with pets i would be concerned about the dog dragging his back legs that is not something that would generally be caused by the routine causes of diarrhea i am pretty confident any veterinarian would suggest the dog needs to be seen probably sooner than later that is not something that over the counter meds would be able to treat
