Pet Equipment Safety: Which Collars, Toys, and Chews Put Your Dog or Cat at Risk?

Walk into any pet store and you are immediately surrounded by shelves promising stronger chew toys, longer-lasting treats, and better solutions for dogs who pull on the leash. It is reasonable to assume that if a product is stocked everywhere, it must be safe. Unfortunately, some of the most widely sold pet products carry real risks that are not at all obvious from the packaging. Prong collars and choke chains can cause neck injuries and worsen behaviour problems. Retractable leashes give dogs too much freedom near traffic and create cord-burn injuries for pets and the people holding them. Popular chews like antlers, rawhide, and bones are among the most common causes of fractured teeth, and everyday toys can become choking hazards or cause surgical emergencies when small parts are swallowed.

At Trafalgar Animal Hospital, we have been caring for pets in Oakville since 1956, and we have seen first-hand how the right equipment choices prevent injuries and make everyday life with a dog easier and safer. We are not here to judge anyone’s gear bag; most of what is on the market today was recommended by a well-meaning trainer, friend, or sales clerk along the way, and it is hard to know what to trust. We just want you to have better information so you can make confident choices. Contact us at 905-845-2611 or text us at 705-980-0932 to schedule a wellness visit where we can assess your pet’s equipment and talk through safer alternatives together.

What Your Dog’s Body Language Is Telling You

Reading dog body language changes how you evaluate equipment. Your dog cannot say “this pinches” or “I really hate when you put that on me,” but they are communicating constantly through their posture, their ears, and how they carry themselves. Canine body language communicates discomfort long before growling or snapping shows up.

Watch for these stress signals when fitting or using equipment:

  • Lip licking or stress yawning during the interaction
  • Ears pinned back or held flat
  • Tail tucked under or carried low
  • Moving away when the equipment is produced
  • Stiffening or freezing when put on

When your dog consistently resists a collar or harness being put on, they are not being difficult or dramatic; they are telling you something real about the experience. Catching those signals early is one of the kindest things you can do for your dog, because it keeps small discomforts from turning into a dog who genuinely dreads getting ready for walks.

Why Reward-Based Training Changes What Equipment You Need

Dogs, much like people, learn faster and hold on to good habits longer when they are working to earn something they love rather than trying to avoid something unpleasant. That one shift completely changes what gear you actually need.

Positive training focuses on rewarding the behaviours you want to see, making those behaviours more likely to be offered willingly. Dogs who learn to walk politely on leash through reward-based methods do not need a device that suppresses pulling through pain or discomfort.

Tools designed around aversive pressure work by making an unwanted behaviour unpleasant. The problem is that this suppresses behaviour without teaching the alternative, and often creates associations between pain and whatever your dog happens to be looking at in that moment. When your dog lunges at another dog and feels a prong tighten each time, they often learn that other dogs predict pain, which makes reactivity worse rather than better. Leash reactivity is one behaviour that consistently worsens with aversive equipment. The engage-disengage game is a practical reward-based approach for reactive dogs that addresses the underlying anxiety rather than suppressing the response.

Equipment to Avoid

Prong Collars and Choke Chains

Prong collars and choke chains work by constricting around the neck when a dog pulls. The mechanism is the same as if you wore a necklace that pinched every time you walked too fast. The dangers of training collars include tracheal damage, cervical vertebral injury, thyroid gland compression, and nerve damage from repeated application of force to the neck. Aversive training methods also carry documented behavioural consequences, including increased aggression and fear responses.

Major veterinary and animal welfare organisations in Canada and internationally recommend against these tools, and our practice aligns with those recommendations. If you have one of these collars at home, please do not feel bad about having used it. The marketing around these products is sophisticated, and they are sold openly in every major pet store. The good news is that a well-fitted harness can replace it immediately, and most dogs respond so quickly to the change that you will wonder why anyone ever uses the other option.

Retractable Leashes

Picture the scene: your dog spots a squirrel and takes off at full speed toward the curb. With a traditional leash, you have an immediate stopping point and a secure grip. With a retractable leash, there is a split second where you instinctively grab the cord to pull them back, and that thin cord burns through skin quickly. These injuries come in to both veterinary and human emergency departments regularly.

Retractable leash risks include the thin cord wrapping around fingers, wrists, and legs, causing serious friction burns and lacerations. Retractable leash injuries requiring medical treatment are well documented in both people and pets. These leashes also provide little meaningful control when a dog suddenly pulls toward traffic or another animal, a real concern on Oakville’s busy streets.

Beyond safety, retractable leashes actively reinforce pulling. When pulling extends the lead, your dog learns that pulling works. The very tool meant to give you flexibility often ends up training the exact habit you are trying to break.

Safer Walking Equipment

Harnesses distribute pressure across the chest and shoulders rather than the neck. For dogs who pull, front-clip harnesses redirect the pulling motion back toward you, interrupting the behaviour without pain. Back-clip harnesses work well for dogs who already walk calmly.

Choosing the right collar depends on your dog’s size, anatomy, behaviour, and any health history relevant to the neck and throat. A flat buckle or martingale collar for ID and a front-clip harness for walks is a sensible combination for many dogs.

A standard 1.5 to 2 metre leash provides the best balance of control and freedom for everyday walks. For recall practice or off-leash training in open spaces, a long line of 5 to 10 metres offers freedom without the cord hazard of retractable designs. Long line training builds recall reliably in a controlled way. Walking nicely on leash is a skill that develops with consistent reward-based practice, not equipment that makes pulling painful.

Dangerous Toys

Dogs chew for all sorts of reasons: boredom, anxiety, teething, and the simple satisfaction of breaking something down. The trouble is that once a piece breaks off a toy, most dogs will swallow it rather than spit it out, which is how toys end up on operating tables. Gastrointestinal foreign bodies requiring surgical removal are one of the most common emergencies in dogs, and toy parts are frequently the cause. The pieces that seem small enough to ignore can lodge anywhere from the oesophagus to the intestines.

Common hazardous toys:

  • Tennis balls: the abrasive felt cover wears tooth enamel with regular hard chewing; larger dogs can compress the ball enough to create a lodging risk
  • Rope toys: individual fibres swallowed separately form linear foreign bodies that wrap around intestinal structures, requiring emergency surgery
  • Squeaky toys: once the squeaker is extracted, the small plastic piece becomes a choking and swallowing hazard
  • Undersized toys: any toy that fits past the back molars or could be swallowed whole is too small for that dog
  • Hard plastic toys: can shatter into sharp fragments that lacerate the mouth and GI tract

Always supervise play, give toys a quick once-over after every use, and retire any toy that is torn, missing pieces, or has been chewed down to a swallowable size. A favourite toy is not worth an emergency trip. Should you find yourself questioning where a squeaker has gone or if your dog is showing signs of vomiting or lack of appetite after eating a toy, we are available for emergency care during our regular business hours.

Dangerous Chews

Dangerous dog chews including antlers, hooves, cooked bones, raw bones, rawhide, and hard nylon products are marketed enthusiastically despite causing the injuries we see regularly. It is worth saying plainly: if these products were as safe as their packaging suggests, we would see far fewer fractured teeth than we do. Dangerous chew items cause:

  • Slab fractures: a tooth breaks along a large surface when a hard object is chewed; painful, infection-prone, and requiring extraction or root canal
  • Choking and intestinal blockages: from swallowed fragments, particularly rawhide pieces that soften into a sticky mass

The thumbnail test: Press your thumbnail firmly into the chew. If it does not leave a dent, the product is hard enough to fracture a tooth. Antlers, hooves, and bones fail this test immediately.

We treat fractured teeth regularly as part of our comprehensive dental care. Prevention through product selection is simpler and less expensive than the treatment, and your dog would much rather keep the tooth than lose it.

Safer Chew Alternatives

It helps to think of chews in two simple categories. The first is consumables that actually break down when chewed, like softer dental chews and pressed edible products. The second is reusables that are tough enough to resist damage, like thick rubber toys. The chews to avoid sit in the middle: rigid items that neither break down nor flex under bite pressure, which is exactly where antlers, hooves, and most bones land.

Safe chew toys flex and compress under jaw pressure. Durable rubber toys that can be stuffed with food provide extended engagement safely and redirect chewing energy productively. Stuffing and freezing one for restless evenings is a simple way to keep a busy dog occupied without offering anything dangerous.

Edible dental chews that soften while being chewed provide both mechanical plaque removal and enzymatic benefit. Apply the thumbnail test before introducing any new product. Match chew size to body weight, and supervise initial sessions with anything new until you understand how your dog approaches it. Some dogs work on a new chew gently for weeks; others will break it down and swallow pieces in the first sitting, and that difference matters.

Behaviour and Equipment Go Together

Equipment choices alone rarely resolve behaviour problems. If your dog pulls compulsively, reacts aggressively, or destroys every toy within minutes, they may need more enrichment, more structured activity, or a behavioural assessment that looks at what is actually driving the behaviour. Sometimes what looks like a training problem is actually pain, underlying anxiety, or a simple mismatch between energy level and daily routine. Our team can discuss behaviour concerns during wellness visits and help distinguish between training needs, equipment issues, and medical contributors.

Warning Signs That Need Veterinary Attention

If your pet has swallowed part of a toy or chew, or if you notice these signs after a play session, call us right away:

  • Gagging, retching without producing anything
  • Pawing at the mouth or excessive drooling
  • Blood from the mouth
  • Vomiting or food refusal after chewing
  • Abdominal pain or visible distension

Our diagnostics include imaging to detect foreign material that is not visible externally, and we perform surgical foreign body removals in-house.

Frequently Asked Questions

Are prong collars legal in Canada?

They are not prohibited federally in Canada, but their use is increasingly discouraged by veterinary and animal welfare organisations. Several municipalities have restrictions. Regardless of legality, we recommend against them based on their injury and behavioural risk profile.

How do I know if a toy is the right size?

If the toy fits past the back teeth or could potentially be swallowed whole, it is too small. When in doubt, go larger. Most dogs are perfectly happy with a toy that is a size up from what the packaging suggests for their weight.

What if my dog has been using the same equipment for years without a problem?

Cumulative damage to the throat and neck from aversive collars may not be immediately obvious, and a toy that has been fine for years may become dangerous as it deteriorates. Regular reassessment of your gear is worthwhile at annual wellness visits, and we are always happy to take a look if you want a second opinion on a specific item.

Can cats face similar risks?

Yes. String, ribbon, and linear materials are particularly dangerous for cats, as swallowed string wraps around intestinal structures and requires surgical removal. Small toy parts are also swallowing risks. If your cat loves batting hair elastics around, they are counting on you to keep those out of reach too.
