A urine acidifier is a compound that is ingested by dogs that changes the pH levels in the urine of dogs, making it more acidic. This is often given to dogs with certain types of urinary or bladder stones in an attempt to dissolve the stones. It may also be used to aid in the effect of antibiotics or to maintain good health in the urinary tract.

Urine acidifers should not be given to dogs with liver or kidney disease. They also should be given with food to reduce the chances of side effects such as loss of appetive, nausea, vomiting or diarrhea. They should not be given to dogs that are pregnant or nursing. They also should not be given to dogs on a prescription diet for urinary stones without consulting your veterinarian first.
Methionine is one of the more common urine acidifiers. It is sold under the brand names Methio-Form and Ammonil. Allergic reactions to methionine may include swelling of the face, seizures, pale gums, or coma. It is only available by prescription and is primarily used for the treatment of urinary or bladder stones.
Methigel is the brand name of a supplemental source of methionine and is available over the counter. It is a gel that is formulated with a flavor that most dogs will like. It is primarily intended to maintain the proper pH level and aid in urinary tract health. It can be found at most pet supply stores.
Ammonium chloride is another common urine acidifer. It is sold for this purpose under the prescription brand name Uroeze, which comes in 200 mg or 400 mg tablets. It can be mixed with food to make it easier to give to the dog. It is primarily used as a treatment for urinary or bladder stones.
Phosphoric acid and cranberries are both natural acidifiers. They aren't as potent as the drugs or supplements, but they don't have any of the side effects or precautions that come with the drugs or supplements either. Phosphoric acid is a common ingredient found in many dog foods. Powdered cranberry can be found at many natural pet supply stores or health food stores. Natural acidifiers are used primarily to aid in the health of urinary tracts.
