After a bath: timing is a clue, not proof
A roll after washing gives you a time relationship. It does not give you a confirmed explanation.
Do not promote the scent theory into a diagnosis
VCA uses the freshly bathed dog to introduce scent camouflage as a theory. The same source explicitly keeps other explanations open. A post-bath roll does not establish that a dog dislikes a product, is trying to hide a smell or has a skin condition.
Preserve product information accurately
Write the actual product name if you know it and retain its label instructions. If someone else bathed the dog, distinguish what they told you from what you saw. Do not enter a guessed ingredient, dilution or application time.
Original editorial recording method. Not a clinical assessment.
Notice other changes without testing the dog
If scratching, licking, rubbing or a visible skin change is present, describe it for the veterinarian. Cornell explains that itch-related disease is assessed through history, examination and exclusion of alternatives. A home rolling test cannot supply that assessment.
Avoid a new experiment
Do not deliberately reapply a suspected product or encourage more rolling to test a theory. The record's purpose is to retain existing observations and questions, not create an exposure experiment. Follow the veterinarian's instructions about any product concern.
