One minute they’re snoozing in their bed, the next they’re going full tornado chasing their own tail like it’s an intruder.
Puppies, right? If you’ve ever caught your little one spinning like a fluffy top or gnawing on their rear like it’s made of bacon, you’re not alone.

Tail biting in puppies is one of those things that looks funny at first, until you start wondering, “Wait, is this normal? Or should I be worried?”
It Might Just Be Puppy Play
Let’s not overthink it straight out the gate. A lot of tail biting is just play behavior. Puppies are curious, bouncy little weirdos. They see something moving behind them and think, “Right, game on!”
Sometimes it’s just them figuring out that their tail is… theirs. If the biting is gentle and playful and they don’t seem stressed, odds are it’s all part of growing up. Kind of like when toddlers try to eat their toes.
Teething Can Get Real Chewy
Between eight weeks and six months, puppies go through teething. And mate, it’s no picnic. Those tiny jaws are looking for anything to bite on, and their tail just happens to be nearby.
Some pups bite their tails because it feels good on their sore gums. Especially if they haven’t got enough chew toys lying around. That’s your cue to up your toy game, rubber rings, frozen carrots, soft toys, the lot.
When Boredom Turns Into A Habit
Picture this: You’re stuck in the house all day with nothing to do. No Netflix. No snacks. No walks. What do you do? Maybe chew your own arm? For pups, that’s kinda what tail biting is when they’re bored out of their little minds.
It usually starts off playful, but if they’ve got too much energy and not enough stimulation, tail chasing can turn into a repetitive habit.
Dogs need things to sniff, chase, tear up, or at least explore. Even a cardboard box filled with safe toys can be a game changer.
What If It’s Something More Serious?
Now here’s where we pump the brakes for a sec. If your puppy is constantly biting their tail, growling while doing it, or yelping in pain, that’s not just boredom. There might be something actually bothering them.
Check for fleas, especially near the base of the tail. You might spot redness, bumps, or flakes. Parasites like worms can also cause discomfort near the bum, and that might lead to the chewing.
Skin allergies or infections can make tails super itchy too. And let’s not forget about anal gland issues, gross but real. If your pup seems obsessed with their tail and nothing calms them down, it’s time to let a vet take a look.
Anxiety Can Show Up In Weird Ways
Some pups bite their tails when they’re anxious or stressed. Maybe there’s a loud bang outside or you’ve just started crate training. Tail biting can be a self-soothing habit, a bit like how some humans bite their nails when they’re nervous.
This is more common in sensitive or high-energy breeds. If your pup tends to freak out during changes in routine or when left alone, anxiety could be playing a part.
In one case I saw at the dog park, a young Labrador kept spinning and chewing at his tail every time his owner walked out of sight. Turns out, the poor thing had separation anxiety. With training and a bit of structure, they got it under control.
Redirection Is Your Best Friend
So, what do you do when the tail biting starts? Don’t shout, don’t punish. Just redirect.
Grab a toy and get their attention. Praise them when they chew the right thing. If they’re really into tail chasing, try tossing a treat-filled puzzle toy their way or even engage in a little tug-of-war.
Consistency is key here. Don’t let them go ham on their tail one day and then scold them for it the next. Make chewing something else way more exciting and rewarding.
Keep Their Environment Enriched
A tired puppy is a good puppy. That’s not just a cute saying, it’s facts. Make sure your dog’s daily routine includes walks, sniff sessions, short training games, and playtime. Mental stimulation works wonders.
Rotate their toys weekly so they don’t get bored. Try snuffle mats, lick mats, or frozen treats in rubber toys. These things are cheap, easy, and give their brains a workout.
Even leaving the telly on or some calm background music can help dogs who struggle when alone. Little things like that go a long way.
When You Should Call The Vet
If the tail biting becomes obsessive, draws blood, or your pup is limping or seems off, don’t wait it out. Call the vet. Better safe than sorry, yeah?
Sometimes a behavioral issue has a medical cause underneath it. Or it could be a combination of both. Either way, vets and behaviorists have seen it all. You’re not being dramatic for asking.
And let’s be real, if you’re waking up at 2am to check if your dog is chewing their tail again, you deserve peace of mind.
Clean-Up Tips If Things Get Messy
Tail biting can sometimes lead to sore spots or open wounds. Keep a pet-safe antiseptic on hand, and don’t let them lick at it. You might need a cone or recovery sleeve if they won’t leave it alone.
If fleas or allergies are part of the problem, wash their bedding, vacuum often, and use treatments that are actually vet-approved. None of that dodgy stuff from random corners of the internet.
And if your pup poops on themselves while spinning, yeah, it happens, baby wipes or a quick rinse in the tub will sort them out. Just don’t make a big deal out of it.
Final Thoughts For Fellow Dog Parents
Watching your puppy bite their tail can be funny, weird, or downright stressful. Some days you’re laughing, some days you’re Googling at 1am wondering if their tail is going to fall off.
But remember, most of the time it’s fixable. With some play, patience, maybe a toy or two, and a good vet in your corner, your pup will be fine.
Hang in there. You’re doing your best. And at the end of the day, we all just want happy, healthy dogs, not a spinning circus act in the living room.
