Most dogs will have their first heat around 6 months of age. Smaller breeds may go into heat sooner than large breeds. Aries may have a UTI (urinary tract infection). Symptoms include frequent urination, straining to urinate, foul smelling or bloody urine and a change in thirst or urination. You would need to have her physically examined by your veterinarian and submit a urine sample, for urinalysis and culture, to definitively diagnose a UTI.
