I agree with the people who think it's urine. Puppy urine doesn't always have a strong smell and can smell like sweat. Since it's only on the back hind leg she's lying on, that's suspicious, because that's where you'd expect urine to flow by gravity. If it were sweat, it would be distributed over her whole body. I agree with yavenay, who suggested waking her up in the middle of the night for a potty break. Then see if your problem disappears. |
