Skin allergies in dogs flare, fade and come back, which makes finding the cause maddening. PetHealthLog lets you log itch level, medications, baths and possible triggers on one timeline - so patterns surface and your vet gets a clear flare history instead of guesswork. Free, no account, works offline.
Skin allergies are one of the most common chronic problems in dogs - itching, licking, ear trouble, hot spots - and they tend to flare and settle rather than stay steady. That on-off pattern is the very thing that makes the trigger hard to pin down.
Was it the new food, the spring pollen, a flea, the shampoo? With flares spread over weeks and treatments changing along the way, it's nearly impossible to connect cause and effect from memory - and that's exactly what your vet needs to narrow things down.
PetHealthLog is free, needs no account and works offline, so logging the itch level, treatments and possible triggers builds the timeline that turns scattered flares into a pattern you and your vet can read.
What the tracker actually does
Log itch level and flares
Record how itchy or sore your dog is, so flares and calm spells form a clear trend instead of a vague memory.
Track medications, baths and supplements
Add allergy medication, medicated baths, omega supplements or a diet trial by schedule and tick each - so the plan is followed and you can see what coincided with relief.
Note possible triggers
Jot food changes, the season, fleas or a new product next to the flares, so patterns between trigger and itch can surface.
Weight and vet visits in one record
Keep weight and vet visits on the same private timeline as the skin history.
A vet-ready PDF
Export a clean record of flares, treatments and triggers, so an allergy work-up with the vet starts from real data.
Common dog skin & allergy care items (#ad)
Allergy medication and any diet trial should be guided by your vet. These are common over-the-counter skin-care items some owners use; match everything to your vet's advice.

Can it help find my dog's allergy trigger?
It can help surface patterns. By logging flares alongside food changes, seasons, fleas and new products on one timeline, you give yourself and your vet a much clearer history to work from - but identifying an allergy usually needs your vet, often with diet trials or testing. The tracker organises the clues; your vet makes the diagnosis.
How do I track whether a treatment is working?
By watching the itch level over time against the treatments you've logged. A steady record shows whether flares are getting less frequent or milder, which is far more reliable than impression. Your vet interprets the trend and adjusts the plan.
Does it work offline?
Yes. PetHealthLog is a progressive web app that works offline, so you can log a flare or a treatment without a connection.
Is this a substitute for veterinary advice?
No. PetHealthLog is a record-keeping tool, not veterinary advice. Skin allergies should be diagnosed and treated by a licensed veterinarian; the tracker just records the flares, treatments and possible triggers you observe.

When to contact a vet immediately
A tracker is for patterns over time — it is not for emergencies. Contact a veterinarian or an emergency clinic right away if your pet has difficulty breathing, collapses or cannot stand, has a seizure that does not stop or seizures that repeat, is straining to urinate without producing urine, has severe bleeding, or may have swallowed something toxic (see ASPCA Animal Poison Control).
