Map the face, ears, paws and belly
Take similar-angle photos and note face rubbing, head shaking, toe licking or belly chewing, with hair loss, darkening, odor, discharge or ear debris. Cats may show over-grooming and thinning coat, while dogs may scratch visibly; appearance alone does not identify the cause.

Record possible triggers separately
Mark timing of diet, parasite prevention, bathing, grass, cleaners, seasons, a new pet, or other pets itching. Avoid changing many things at once; a diet or environmental trial should have veterinary guidance, a defined period and stop criteria.

Broken skin, facial swelling or breathing trouble changes the urgency
Rapid facial swelling, hives with breathing effort or collapse is an emergency. Bleeding from scratching, pus or odor, painful ears, inability to sleep or reduced eating warrants prompt assessment.

Do not mask the pattern with human medicines or constant product changes
Do not give human antihistamines, anti-itch medicine or steroids, and do not layer essential oils, creams or multiple shampoos. Bring product names and ingredients and tell the clinic whether each use helped or worsened signs.
