Why do canines like to play with trash? – Sarah G٫ age 11٫ Seguin٫ Texas
After I take into consideration why canines do one thing, I attempt to think about what motivates them. What does a canine get out of enjoying with trash? As a veterinarian and a professor who teaches school college students about companion animals, I imagine there’s a simple reply: Rubbish smells scrumptious and tastes good to canines.
Canines have an incredible sense of odor. They’ve 300 million receptors for odor of their noses, whereas people have solely 6 million. Folks could make use of this sniffing means to coach canines to detect unlawful medicine, explosives and endangered species, and to assist find folks misplaced within the woods.
When you won’t like how your trash smells, to your canine it’s an interesting buffet brimming with apple cores, banana peels, meat scraps and off bread. Even used napkins and paper towels are tempting to canines, when they’re smeared with and carry the odor of yesterday’s lunch.
As a result of canines can discover hint quantities of explosives or an individual buried beneath 6 toes (1.8 meters) of snow after an avalanche, they’re definitely able to finding final night time’s pizza crust and hen bones within the kitchen rubbish can.
Typically it’s arduous to see what the attraction is. My Australian cattle canine combine, Sparky, likes to eat used tissues – gross, proper?
Even empty cans odor inviting to canines. Trash cans in kitchens and bogs are sometimes at their nostril degree, too, making for simple entry. Add to that the truth that if the canine obtained into the rubbish as soon as and located one thing tasty, they’ll seemingly hold looking with the hope of being rewarded once more.

Thrill of the hunt
Looking out and digging round for meals is pure for canines as a result of it offers a few of the thrill of the hunt, even when they only ate and aren’t hungry.
Essentially the most profitable prehistoric canines ate the bones and scraps that people left behind greater than 10,000 years in the past. Hanging round people and their rubbish was a approach they may get lots to eat. Even your pup right this moment has a few of those self same previous looking instincts.
Whereas our trash has modified from the times of looking and gathering, the discarded paper napkins, plastic wrappers and meals scraps we throw away all nonetheless odor like meals to canines. And this scavenging conduct remains to be hardwired in our pampered pets. Though it could look to us like they’re enjoying, our canines’ sniffing out and tearing issues up from the trash and tossing them round mimics what their ancestors did after they tugged on and tore up an animal carcass they’d discovered.
Many individuals reap the benefits of this intuition and use “snuffle mats” – material or paper the place meals is hidden – or puzzle feeding toys to maintain their pups’ minds energetic. Having to hunt for and discover their meals helps them use their noses and sharpens their abilities.
Annoying and even harmful
Whereas spreading trash everywhere in the house could also be pure for canines, cleansing it up is not any enjoyable for the folks they stay with. And in case your canine pokes its nostril in a rubbish can, it may very well be at risk. Consuming plastic luggage, string, hen bones, chemical compounds or rotten meals may cause blockages, diarrhea and poisoning. Generally known as “garbage gut,” rubbish poisoning will be life-threatening.
I’ve handled canines that reduce their tongues and mouths on cans or damaged glass. I as soon as carried out surgical procedure to take away a corncob from the intestines of a canine that had eaten it a month earlier. He was definitely relieved when he awakened.
How are you going to hold your canines away from the trash?
It may be arduous to coach a canine to go away rubbish alone, particularly if they’ve discovered a tasty morsel or two by raiding the trash can up to now. I like to recommend that you simply put money into a rubbish can with a lid closed by a latch that they’ll’t open. If that fails, you’ll be able to put rubbish – particularly meals scraps – out of attain in a closet, cabinet or behind a closed door.
My trash cans are all behind closed doorways, and the lavatory doorways are all the time shut, which additionally retains my cat, Penny, from unrolling the bathroom tissue. However that’s one other story. Our kitchen trash is in a latched cabinet.
Nobody is aware of precisely what goes by canines’ minds. And but taking a look at what motivates your canine companion and the way canine behaviors have developed might assist clarify why these animals do the issues they do.
And since curiosity has no age restrict – adults, tell us what you’re questioning, too. We gained’t have the ability to reply each query, however we’ll do our greatest.
