Urban Deer and Your Dog: A Vic West Guide to Autumn Encounters
Victoria's urban deer are a year-round fixture, but autumn is when they become unpredictable. The rut runs through October and November, bucks become bold and territorial, and does with late fawns stand their ground. A deer that calmly ignored your dog in July may stand its ground, or come forward, in October.
Why autumn changes the behaviour
For most of the year urban deer around Vic West behave like scenery. They browse gardens, cross roads at their leisure and generally move away from people and dogs.
Two things change in the fall.
The rut. From roughly October into November, bucks are driven by hormones, they carry hard antlers, and their tolerance drops sharply. A buck in rut is genuinely unpredictable and will confront a dog it would have walked away from a month earlier.
Late fawns. Does with fawns still at foot are defensive well into the fall, and a doe protecting a fawn is more dangerous to a dog than most owners expect. Deer defend with their front feet, striking downward, and those strikes cause serious injuries.
Add the earlier darkness, which puts more dog walks into the hours when deer are most active, and autumn is simply the season when encounters go wrong.
What actually happens to dogs
The injuries we see from deer encounters are not scratches. A deer strike can cause:
Blunt force injuries to the chest and abdomen, which frequently show no external wound
Puncture wounds from antlers, which are deep and heavily contaminated
Fractured ribs and limbs
Internal bleeding
Head and eye injuries
Injuries to the handler, since people are struck trying to intervene
The chest and abdomen point matters most. A dog that has been struck and gets up and walks can have significant internal injury with nothing visible from outside. Any dog that has been struck, trampled or thrown by a deer needs to be examined the same day even if it seems fine.
Preventing it, which is mostly about the leash
Almost every serious incident follows the same sequence: a dog off leash sees a deer, chases, and the deer turns.
Keep dogs on leash anywhere deer are present, which in Vic West is most residential streets and green space
Scan before you step out. Deer bed down in gardens and hedges and are easy to walk straight into, particularly at dawn and dusk
Check your own yard before letting a dog out, especially at night. A deer cornered in a fenced yard is the worst possible situation
Do not let your dog chase, ever. Even a dog that "just wants to play" reads as a predator to a deer
Give a very wide berth to any buck, and to any doe with a fawn. Cross the road, turn around, take another route
Do not approach for a photograph. They are wild animals with hooves and antlers, not livestock
Never feed deer. Fed deer lose their wariness entirely, and the ones that lose their wariness are the ones that cause problems
Make yourself known. Speak normally as you approach so a deer is not startled at close range
Use a torch in the dark so you see them before your dog does
If a deer does not move off
Do not turn your back and do not run. Shorten the leash, pick a small dog up if you can do so safely, back away slowly while facing the animal, and put something solid between you if there is anything to hand. A deer that lowers its head, stamps a front foot or flattens its ears is telling you to leave, and you should.
What to do after an encounter
Get your dog away and somewhere quiet before examining anything
Phone us before you start cleaning so you are not making decisions alone
Look over the whole body, parting the coat over the chest, flanks, belly and armpits. Antler punctures are small on the surface
Do not pour anything into a puncture wound, and do not apply anything from your own cabinet
Watch the breathing. Faster breathing, effort at rest, or a dog that will not lie down comfortably points to a chest injury
Note the time and what happened, including whether your dog was struck, thrown or trampled
Come in immediately for difficulty breathing, pale gums, weakness or collapse, a wound anywhere on the chest or abdomen, obvious lameness, or a dog that was trampled. Details of the services we provide are on our what we offer page, and our facility page shows what we have on site.
The other autumn deer problem: ticks
Deer carry ticks, and where deer browse regularly, ticks follow. That means suburban gardens and green edges, not just wilderness trails.
Tick activity does not stop when summer ends. On Vancouver Island the mild wet autumn is an active period, and dogs pick them up in exactly the gardens and verges deer frequent.
Check your dog after walks, particularly around the head, ears, neck, armpits and between the toes. If your dog is not on year-round tick prevention, this is the season to talk to us about whether it should be. There is more on preventive care in our informative articles.
Frequently asked questions
My dog chased a deer and came back fine. Do I need to do anything?
Look him over carefully, including under the coat over the chest and belly, and watch his breathing for the rest of the day. If there was any contact at all, or you did not see the whole encounter, phone us. Blunt chest and abdominal injuries frequently show nothing externally.
Are urban deer actually dangerous?
They are usually indifferent, and that is exactly why people underestimate them. A deer that feels cornered or is defending a fawn, and a buck in rut, are a different proposition. They are large animals with hard hooves and, in autumn, antlers.
When is the rut, and how long does it last?
Roughly October through November, with the peak usually in November. Bucks become noticeably bolder and less predictable through that window, so it is worth being more careful about route and leash for those two months than at other times of year.
A deer keeps coming into my yard. What can I do?
Remove what is drawing it in, which is usually accessible plants, fallen fruit or anything being fed. Fencing helps if it is high enough. Check the yard before letting a dog out. Do not try to chase a deer off yourself, particularly in autumn.
Do deer carry anything my dog can catch?
Not directly in any common way, but they bring ticks into gardens and green space, which is the practical risk. Regular checks after walks and a conversation with us about year-round prevention are the sensible response.
My cat goes outside. Is she at risk?
Deer encounters are much less of an issue for cats, which avoid them. Ticks are the shared risk, so check your cat too, and speak to us about what prevention is appropriate, since products suitable for dogs are frequently dangerous to cats.
