Hi Marion, actually the symptom of your pup may very well be secondary to a urinary tract infection. It can cause urinary retention due to dysuria (pain upon urination). That may have caused your pup to be uncomfortable. It is common for urine tests to show some crystals but that doesn’t necessarily mean that your pup has struvite stones in the bladder or any other stone. Antibiotics will solve dysuria. However I suggest you take an xray rather than urine testing strips to confirm presence of bladder stones outright.
