Why does my dog lick up another dog's pee? Is it a health concern?

Updated On September 23rd, 2025

Pet's info: Dog | English Cocker Spaniel | Male | unneutered | 11 years and 2 months old | 25 lbs

My Hannah is a 13 yr old lab mix that had bladder crystals until the age of 3. Now when she pees, Remington, intact male English Cocked Spaniel, will fight to get to where she went and try and lick it up. Why?

This is a tricky situation and could have several possibilities. Monitor Hannah's drinking and urination volumes closely. If they have increased, consider having her examined and evaluated for diabetes mellitus, as would cause glucose (sugar) to spill into her urine, making it sweet and possibly more palatable for Remington. Otherwise, if Remington has been licking Hannah's urine and other items obsessively, this could be a sign of nausea (although this seems like a stretch). This is unusual behavior and I think that the best course of action would be to start by taking Hannah to her vet for a urinalysis to determine if there is glucose in her urine, crystals or signs of infection that may be tempting to Remington.
