Observations
Dog scratching but no fleas: the record that helps your veterinarian
Your dog keeps scratching and nothing turns up when you search through the coat. That result is worth writing down — and so is almost everything else you can see from home. This page is about the record: how often it happens, where on the body, at what times, and what changed beforehand. What the scratching means is a question for a veterinary examination.

Why does a record help your veterinarian?
A veterinarian can only work with what they are told and what they can see in the room. Dogs often behave differently in an unfamiliar place, so the scratching you see at home may not happen there. A dated record carries that part of the story with you: the frequency, the places on the body, the time of day and what changed beforehand.
The record has four parts — how often, where, when, and what changed. None of them asks you to guess a reason, and none of them is a diagnosis. They are observations, written in the same ordinary words you would use with a neighbour.
For the skin and coat themselves — colour, texture, smell, thinning coat — the full observation guide covers what to look for.
How do you record scratching so a veterinarian can use it?
Use the same few fields each time and the same words for the same things. A note made when it happens can be compared with yesterday; an account written from memory the night before an appointment cannot.
For frequency, prefer counting to impressions. “Twice before breakfast, then not again until the evening” tells your veterinarian more than “a lot”. If you cannot catch each episode, note the moments you did see it.
For timing, note the part of the day or night: during walks, after meals, overnight, at rest. Do not interpret; just write when it happened.
For places, name the body part and the side, the same way each time. “Inside of the left front leg” can be compared; “the usual place” cannot. Note whether the scratching stays in one spot or moves around.
For amount, use words you can keep constant — “more than yesterday”, “about the same as this morning”, “only in the evening”. What those words are matters less than using the same ones next time.
What else can you see while it happens?
Where the scratching happens describes the moment, even though it explains nothing. Note the surface and the setting: on the bedding, on the sofa, on grass during a walk, on a hard floor. Note anything visible on the skin afterwards, in plain descriptive words.
Sleep is the detail owners forget most often. Note whether the scratching interrupts your dog’s rest, whether it wakes you, and whether your dog settles again afterwards. You are not measuring anything — “woke us in the night, settled after going outside” is a complete entry.
If you noticed more than one thing — scratching, plus redder skin, plus a scab — give each its own line. Observations that stay separable can be compared; observations bundled into one story cannot.
When to stop reading and book an appointment
This is the part of the page that matters most. Persistent itch, hair loss, odour, open lesions, ear involvement or a sudden change are each a reason to book an appointment. Painful, open or worsening skin also needs veterinary attention. You do not need to finish a record before calling.
A record supports the conversation; it is never a reason to wait. Start the notes on the way, not instead of the call.
For difficulty breathing, collapse or unresponsiveness, uncontrolled bleeding, seizures, or suspected poisoning, contact emergency veterinary care now.
What counts as “what changed”?
The fourth field is the easiest to skip and the most useful later. Note anything new in your dog’s routine, even if it seems unrelated: a wash with a different product, a change of food, a new bed or blanket, a move, a different walking route, a season turning, building work, another animal visiting.
Include what you have already checked, too. If you searched through the coat and found nothing, write that down with the date: “searched the coat carefully, found nothing” is an observation, and a useful one. What the result means is not something a note can settle.
Do not change food, routine or anything else because of a pattern in your notes; those decisions belong to your veterinarian. For the full written record, photographs included, the six details worth writing down extend this list.
What will the veterinarian ask that your record answers?
Most questions come straight from the four fields: Where is it most often? When did you first notice it? Has it changed since? What was different beforehand? An entry written when it happened answers these from the page instead of from memory.
Bring the record in a form somebody else can read in a minute: dates down one side, a line per entry, photographs next to the day they belong to. For a packing list and the questions worth bringing, see preparing for the appointment itself.
- The date and the time of day of each entry.
- Where on the body: the part, the side, whether it stayed put or moved.
- How much, in your own comparable words: “more than yesterday”, “about the same”, “only in the evening”.
- What it interrupted: rest, sleep, a walk, a meal.
- What the skin and coat looked like where it happened, in ordinary descriptive words.
- What changed beforehand: washes, food, home, bedding, routes, seasons.
- What you already searched for and found, with the date of the search.
- Your questions, written down before you arrive.
What can a record not tell you?
A record cannot identify the cause of scratching, tell you how serious a change is, or confirm that it is safe to wait. Those answers need a veterinary examination, sometimes with tests. The boundary is worth stating plainly on a page about observing: describing what is on the dog is factual, and explaining why it is there is diagnosis — which is not something notes, photographs or this website can do.
General information, including everything on this page, cannot settle what is normal for your dog. Cori is a record-keeping tool in development; the waitlist for itchy dogs explains what is planned. Whatever you use to keep the notes, the record itself is the useful part.
Why is my dog scratching when I can’t find fleas?
Because “why” is the one part the search cannot answer. A careful search of the coat that finds nothing is an observation: it records what the search found, on that day, in that light, by that person. Scratching with nothing found is not a puzzle to solve at home. It is two observations worth bringing to a veterinarian, who can examine the skin itself rather than read about it.
How much scratching is normal for a dog?
There is no number on this page, on purpose. Scratching varies between dogs, with coat, with season and with the moment, and a single figure would invite you to place your own dog on a scale this page cannot support. What you can compare is what you have seen: more or less than yesterday, earlier or later in the day, the same places or new ones. Whether what you see needs attention is a question for your veterinarian.
Should I still record scratching that comes and goes?
Yes. Scratching that comes and goes is the pattern most easily misremembered. Note the moments you see it and, roughly, when you did not; a gap in the notes is information too. “Nothing noticed” is a valid entry, and it keeps the record honest without asking you to explain the gaps.
What if I am not sure whether it is scratching, licking or chewing?
Write the motion you saw, in plain words: “licking the left front paw”, “chewing at the base of the tail”. You do not need the right category; you need the same words next time. The place on the body and the moment matter more than the label, and your veterinarian is used to working from owner descriptions.
Can I show my veterinarian a video instead?
A short video is a good supplement: it shows the motion and the body area exactly as they were, including in the night, when the appointment cannot. Keep it brief, keep it dated, and keep the written record as the backbone. A video answers “what did it look like”, not “how often” or “what changed”.
Does keeping a record mean waiting to contact a veterinarian?
No. Recording is something you do on the way, not instead of going. The signs listed under “When to stop reading and book an appointment” above are each a reason to book before writing anything else, and you never need a finished record first.
