How can I estimate my female dog's urine volume? I know human urine flow is about 1 oz/second. Trying to determine if she might have polyuria.

If your dog has polyuria, she will also have polydipsia. So you can measure the amount she drinks in 24 hours: give her a large bowl of water full to the brim, then fill it up again after 24 hours and measure the amount you have to refill. Your dog should not drink more than 1300ml in 24 hrs. (44 fl oz). If she drinks significantly more (polydipsia) than that she is ls likely polyuric as well and needs to be seen by a veterinarian for an exam.
