Cautions: Allopurinol should be given with meals. It should not be given to pregnant or nursing animals and should not be used in puppies.

my app. 11 yr old heinz 57 dog that I have no history on has been vomiting yellow bile looking fluid last two-three days but is eating,urinating,bowels o.k. and every other aspect o.k. Any suggestions or just see our vet ?
My 5 lb. 11 year yorkie has suffered from stones all her life. Ultasounds showed that her kidneys contain many stones. The last stone she passed was a urate stone. However, I believe she may have had struvite stones in the past, but not sure.
Allopurinol is used in the treatment of urate stones. Struvite stones are dissolved by making the urine acidic. Methio-Form is a urinary acidifier available by prescription. There are diets available to treat struvite stones as well.
Calcium oxalate stones are usually removed surgically. However, with proper diet and drinking plenty of fluids the chance of formation is reduced. Calcium citrate (Urocit-K) is a prescription medication used to reduce formation of calcium oxalate stones.
