Tracking Dog Allergy Symptoms

I have written elsewhere about how I approach allergy diagnosis step by step, from parasite treatment through diet trials to immunotherapy. This article is about the part of that process that lives entirely with the owner: The symptom record. It sounds mundane next to blood samples and hydrolyzed diets, but said plainly: A good symptom diary shortens allergy workups. The diagnosis is largely detective work, and the diary is evidence.
Why memory is not enough
Allergy patterns play out over months and years. Few can honestly compare this July's itching to last July's from memory, and consultations that start with 'He's been itchy on and off, worse sometimes' provide very little to reason from. Compare that with a record showing symptoms rising every May through July with quiet winters: that pattern alone points toward pollen before any test is run.
What log log during a flare:
The symptoms themselves: Ear itching, skin itching and redness, paw licking, head shaking, and any stomach signs like soft stool or gas.
Severity scored simply. 0-5 per symptoms is enough. Scoring is what turns 'worse' and 'a bit better' into something measurable across weeks.
The date. This is the whole point; seasonal patterns are made of dates.
Photos. Skin redness has an impressive talent for fading the morning of the vet appointment.
Context. New food or treats, walks in tall grass, a bath, flea/tick treatment status, new bedding or detergent.
And just as important: log some symptom-free days. A record containing only bad days exaggerates the disease and hides improvement, which matters when we are judging whether a treatment works or environmental or seasonal factors.
How this looks in PetVitality
The allergy tracker uses severity sliders for the main symptoms plus a vocabulary of additional ones, with notes and photos on each entry. Confirmed allergens are stored on your pet's profile, and they carry over automatically into the pet sitter PDF, so the wrong treat does not get fed while you are away. The app charts symptom intensities across the year, which is exactly the view that makes a seasonal pattern jump out, and the full history exports to PDF for veterinary visits or diet trial reviews.
Using the pattern
The practical handoff of a season pattern is timing. If the record shows flares starting in May, you and your vet can plan: Begin treatment in late April instead of chasing a flare in June, and stock up before the itch arrives. Getting ahead is cheaper and considerably more comfortable for your dog.
