Quick answer: Before the year ends, book your dog’s annual wellness exam, check which vaccines are due, and confirm heartworm, flea and tick prevention is up to date. Look at your dog’s teeth and weight, update microchip registration and ID tags, refill medications and toss expired ones, and review pet insurance or wellness plan benefits before they reset. Then organize medical records, restock your dog first aid kit and add next year’s vet visits, vaccine dates and monthly preventives to your calendar.

The end of the year is a natural time to take stock, and that includes your dog’s health. Between holiday plans and busy schedules, it is easy for an overdue vaccine, a lapsed preventive or an old microchip phone number to slip through the cracks.

A short year-end review can catch small problems early, help you make the most of any pet insurance or wellness plan you pay for and set your dog up for a healthy start to the new year.

This checklist walks through 12 things to do before the new year, from booking the vet and checking vaccines to updating ID, organizing records and planning next year’s care calendar.

Why do a year-end health check for your dog?

Dogs age faster than we do, so a year in a dog’s life is a meaningful amount of time. Changes in weight, teeth, joints or behavior can creep up slowly and are easy to miss day to day.

A year-end review gives you a regular moment to step back. It turns scattered tasks into one simple routine, so nothing important gets forgotten between busy months.

It can also save money. Many pet insurance policies and wellness plans run on a yearly cycle, and some benefits do not roll over. Using them before they reset can cover care you were planning anyway.

Finally, the holidays bring their own risks, from rich food to travel and visitors. Being up to date on vaccines, preventives and ID before the busiest weeks of the year gives you extra peace of mind.

When should my dog have an annual vet exam?

Most healthy adult dogs should see the vet at least once a year for a wellness exam. Puppies need more frequent visits for vaccines, and many vets recommend checkups every six months for senior dogs and dogs with ongoing health conditions.

Book early. December is a busy month for clinics, and many have reduced hours over the holidays. Scheduling in October or November gives you more choice of dates and time to follow up on anything your vet finds.

Come prepared. Write down any changes you have noticed: appetite, thirst, weight, energy, coughing, limping, lumps, bad breath, itching or behavior changes. Bring a list of current food, treats, supplements and medications.

Ask about the right tests for your dog’s age and lifestyle. Your vet may recommend bloodwork, a urine test, a fecal test for parasites or a heartworm test as part of the annual visit.

Which dog vaccines should I check before the new year?

Core vaccines are recommended for most dogs. They usually include rabies and the combination vaccine that protects against distemper, adenovirus and parvovirus. Rabies is also required by law in many places, and timing depends on local rules and the vaccine used.

Lifestyle vaccines depend on where you live and what your dog does. These may include leptospirosis, Bordetella for kennel cough, canine influenza and Lyme disease. Dogs who board, go to daycare, visit groomers or spend time in the woods may need some of these.

Check your dog’s records for due dates. If you are traveling or boarding your dog over the holidays, many facilities require proof of current vaccines, sometimes given at least a week or two before the stay.

Talk with your vet about which vaccines make sense for your dog and how often they are needed. Guidelines change, and your vet can tailor a schedule to your dog’s age, health and lifestyle.

Do dogs need flea, tick and heartworm prevention in winter?

Many vets recommend year round parasite prevention. The American Heartworm Society recommends giving heartworm prevention all year, along with an annual heartworm test. Mosquitoes can survive indoors and in warm spells, and gaps in prevention leave dogs at risk.

Fleas can live indoors through winter, especially in warm homes. Ticks can be active on mild days, even in cold regions. Stopping prevention in fall can make it easier for an infestation to start.

Check your supply. Count how many doses you have left and order more before you run out. Set a monthly reminder on your phone for chewables or topical products so you never miss a dose.

Ask your vet about intestinal parasites too. A yearly fecal test and regular deworming, if recommended, help protect both your dog and your family.

How do I check my dog’s teeth at home?

Dental disease is one of the most common health problems in adult dogs. Lift your dog’s lips gently and look at the teeth and gums. Healthy gums are usually pink, without redness, swelling or bleeding along the gum line.

Warning signs include bad breath, yellow or brown buildup, red or bleeding gums, broken teeth, drooling, pawing at the mouth and chewing on one side. Some dogs with painful mouths still eat normally, so do not rely on appetite alone.

Ask your vet whether your dog needs a professional dental cleaning. Cleanings are done under anesthesia so the vet can clean below the gum line and take dental x rays if needed.

Make home care part of your new year routine. Daily brushing with a dog toothpaste is the gold standard. Dental chews and water additives can help as extras. See our guide to dog dental care at home for a step by step routine.

How do I know if my dog is a healthy weight?

Weight gain is easy to miss, especially in winter when activity drops and holiday treats increase. Use a body condition check at home. You should be able to feel your dog’s ribs easily with light pressure, see a waist from above and see a tuck behind the ribs from the side.

If you cannot feel the ribs or your dog has no visible waist, they may be carrying extra weight. If ribs, spine and hip bones are very visible, your dog may be underweight. Your vet can score your dog and set a target.

Extra weight affects joints, breathing, energy and lifespan. Even a few pounds matters on a small dog. Ask your vet how many calories your dog needs and measure meals with a cup or kitchen scale.

Weigh your dog at the vet or at home and write it down. Tracking weight a few times a year makes it much easier to catch changes early.

How do I update my dog’s microchip and ID tag?

A microchip only works if the registration details are current. Find your dog’s chip number on adoption papers or vet records, or ask your vet to scan it. Then look up the chip number on the microchip company’s website or a universal lookup tool.

Update your phone number, address and email if anything has changed this year, and add a backup contact. Many lost dogs are scanned successfully but cannot be returned because the details are out of date.

Check your dog’s ID tag. Make sure it is readable and shows at least one working phone number. Replace worn tags and make sure the collar fits well, with room for two fingers underneath.

Holidays and New Year’s Eve fireworks are times when many dogs slip out or bolt. Doing this check in December gives you peace of mind before the busiest nights of the year.

Should I check my dog’s medications at the end of the year?

Yes. Gather every medication, supplement and preventive your dog uses and check the labels. Look at the expiration dates, how many doses are left and how many refills remain.

Refill anything that will run out over the holidays, when clinics and pharmacies may have limited hours. If your dog takes a daily medication, keep at least a two week buffer at home.

Dispose of expired or unused medications safely. Many pharmacies and communities offer take back programs. Do not flush medications unless the label says to, and never give a dog medication prescribed for another pet or person.

Make a simple list of your dog’s medications with the dose, timing and prescribing vet. Store it with your dog’s records and share it with anyone who cares for your dog while you travel.

How do I make the most of pet insurance and wellness plans before they reset?

Review your policy or plan before the year ends. Note your deductible, how much you have already paid toward it and whether it resets on January 1 or on your policy anniversary date.

Wellness plans often include a set number of exams, vaccines, tests or dental services each year. If benefits do not roll over, schedule any remaining covered care now.

Think about next year’s budget. Add up what you spent on food, preventives, vet visits, grooming and supplies this year. It is a useful starting point for planning, and it can help you decide whether insurance or a wellness plan makes sense for your dog.

If you do not have insurance, consider setting aside a small amount each month in a pet emergency fund. Unexpected vet bills are one of the most common money stresses for pet parents.

How should I organize my dog’s health records?

Keep all your dog’s records in one place. That includes vaccine certificates, exam summaries, test results, medication lists, microchip number, insurance details and your vet’s contact information.

Go digital. Ask your vet for an electronic copy of your dog’s records or use a pet health app. Take photos of paper documents and store them in a folder on your phone or cloud storage.

Add a recent clear photo of your dog from the front and side. If your dog ever goes missing, having a good photo ready makes it easier to make flyers and share online.

Share access with a trusted family member or pet sitter. If you travel over the holidays, leave a printed summary with whoever is caring for your dog.

What should be in a dog first aid kit?

A first aid kit helps you handle small problems and stay calm during bigger ones. Basic supplies include gauze pads, a roll of gauze, self adhesive bandage, medical tape, blunt tip scissors, tweezers, a tick remover, saline wash, disposable gloves and a digital thermometer.

Add a few dog specific items: a soft muzzle or a strip of cloth, a slip lead, a towel or blanket, a small flashlight, cold packs, a few days of your dog’s food and any medications they take.

Keep important numbers inside the kit: your vet, the nearest 24 hour emergency clinic and an animal poison control service such as ASPCA Animal Poison Control. Add a copy of your dog’s medical summary.

Check the kit once a year. Replace expired items, used supplies and anything that has been damaged. Keep a smaller version in your car for road trips and holiday travel.

What grooming checks should I do at the end of the year?

Nails: long nails can change how a dog walks and cause slipping on indoor floors. Trim them or ask your groomer or vet tech to help. If you hear clicking on hard floors, it is usually time for a trim.

Skin and coat: run your hands over your dog’s whole body. Look for lumps, bumps, scabs, dry patches, hot spots, fleas or ticks. Note the size and location of any new lumps and show them to your vet.

Ears and eyes: healthy ears are clean and do not smell. Redness, discharge, head shaking or scratching can point to infection. Watch for eye redness, cloudiness or discharge.

Paws: check between the toes and on pads, especially in winter when salt and ice can cause cracks. Keep the fur between toes trimmed and use a paw balm if pads are dry. See our guide to how often to bathe your dog for coat care tips.

What extra health checks do senior dogs need?

Many dogs are considered seniors around seven years old, and large and giant breeds often age sooner. Older dogs benefit from more frequent checkups, often every six months, because problems can develop faster.

Ask your vet about senior screening. Bloodwork, urine tests and blood pressure checks can find early kidney, liver, thyroid and other changes before your dog shows obvious signs.

Watch for changes at home: stiffness when getting up, trouble on stairs, drinking or peeing more, weight loss, new lumps, cloudy eyes, hearing loss, confusion at night or changes in sleep. Write them down and share them at the next visit.

Small adjustments help a lot. A supportive bed, rugs on slippery floors, ramps for the car or couch and shorter, more frequent walks can keep a senior dog comfortable and active through the new year.

What should I ask my vet at the year-end visit?

A few good questions help you get the most from the appointment. Start with the big picture: is my dog at a healthy weight, and what should we work on next year?

Ask about prevention: which vaccines are due and when, which parasite products you recommend for our area and whether my dog needs a dental cleaning soon.

Ask about age and breed risks: are there health problems common in my dog’s breed or size, and are there tests or early signs I should watch for?

Ask about daily care: how much should I feed, is my dog getting enough exercise and are there any supplements or diet changes that make sense? Write the answers down or ask for a visit summary so you can add the plan to your calendar.

How do I plan my dog’s health calendar for next year?

Start with the dates you already know. Add your dog’s next annual exam, vaccine due dates, heartworm test and any follow up visits your vet recommended to your calendar.

Set recurring reminders for monthly flea, tick and heartworm prevention, daily or weekly tooth brushing, monthly nail trims and a quarterly weigh in.

Add seasonal reminders too: check allergies in spring, review heat safety before summer, book holiday boarding early and redo this year-end checklist next fall.

Share the calendar with everyone in your household. When the whole family knows the plan, your dog gets more consistent care and you get a little less on your own plate.
