The following is a list of things that people have seen in their dogs while going through TPLO recovery.  They are divided into things that were considered, by their vets, to be normal and things that were a cause for concern or a call to the vet.  If you are uncomfortable with the way your dog is acting, however, call.  Your peace of mind is worth  much.  This is only a list of other's experiences.  We are not vets or medical people.
What's Normal?

Blood around staples
Strike through bleeding (comes through the bandages)
Swelling at ankles
Leg jerks and muscle spasms
Leg muscle "ticking"
fluid buildup at knee around Day 6
Shaky leg
Rashes and itching
Hot spots
Leaking wounds
Does lie on TPLO leg or won't lie on TPLO leg (both are normal)
Pocket of fluid along incision line
Aversion to the sling
Aversion to the ramps
Sneaking onto beds, stairs and other places they don't belong    :-)
  Having trouble peeing and wanting to "hold it"
Not pooping for the first 2 or 3 days
Panting, whining and restlessnes.  Some panting, whining and restlessness may be normal at first but excessive panting, whining and restlessness could be signs that the dog needs more pain medication or that he is in distress and there is something wrong with the leg.  You have to guage what is normal for your dog. 
What's Not Normal
Blood in Urine
Infections of any kind
Sustained swelling and tenderness
Refusal to put weight on the leg after several weeks
Fever
