One commonly used drug for relieving the body of bacteria is called trimethoprim. Like all prescription medication there is the risk of side effects when using trimethoprim. Always follow dosing instructions to assure the best experience with trimethoprim for your dog.

Dehydrated dogs should not use trimotheprim. If your dog has a blood cell abnormality like anemia, then use trimethoprim with caution and keep a close eye on your dog while he is taking trimethoprim.
Harmless Side Effect
The most common side effect found when treating your dog with
trimethoprim is the appearance of sulfa crystals in the urine, which can
only be found through testing the urine at your veterinarian's office.
This will only become a problem if your dog becomes dehydrated, so make
sure to keep an eye on his water source and keep it filled while you are
giving him trimethoprim. If you are currently giving your dog any other
medication make sure to consult your veterinarian before using trimethoprim, because not all medication mixes well and it may increase
the chances of dangerous side effects.
Other Side Effects
A less common side effect of trimethoprim is dry eyes. also known as keratoconjunctivitis sicca. This is most common when using trimethoprim as a long-term medication.

If any of these symptoms occur within your dog you should stop use of trimethoprim immediately and consult your veterinarian.
Anemia is another rare side effect that has its own wide range of
side effects. The most common signs of anemia are pale gums and
tiredness, and if anemia is affecting your dog you will also find he has
a low platelet level. This will increase the chances of bleeding, a
loss of appetite, diarrhea and vomiting. Anemia can also cause joint
inflammation which could lead to lameness, as well as kidney damage
which can lead to an increase in thirst and urination.
If your
dog shows any of the above mentioned signs you should stop usage of trimethoprim and consult your veterinarian immediately.
