Pet Gear That Can Actually Cause Injury (and What to Use Instead)

Here is something nobody puts in the product description: “may injure your pet under normal use.” The pet accessory market is enormous and not always well regulated, and some of the most popular items, including retractable leashes, prong collars, certain harnesses, chew toys, and squeaker toys, carry real injury risks that most families have never been warned about. It is not about being alarmist; it is about understanding that certain designs cause certain problems, and that better options exist.

Animal Hospital Southwest in Fort Worth has seen the aftermath of equipment and toy-related injuries more times than we would like, and we are happy to be the kind of practice that has the frank conversation about gear. Our emergency care is here when something does go wrong during open hours, but we would rather help you avoid the visit entirely with the right info upfront. Book an appointment any time you want to talk gear, training, picking the right toys, or anything else with our team.

Reading Your Pet’s Body Language Before You Pick Out Gear

Before we get into specific products, a quick aside that genuinely matters: dogs and cats tell you when something is wrong, but they tell you in their own language. A dog who freezes when you reach for the leash, lip-licks during the harness-on routine, or pins their ears flat as soon as the gear comes out is communicating discomfort, not being dramatic. Learning the basics of body language gives you a head start at picking gear your pet actually tolerates.

Subtle stress signals worth noting include yawning out of context, looking away, a tense or held breath, a tucked tail, or a low body posture. More obvious signs include backing away, growling, or trying to slip out of the gear. Cats tend to communicate with tail position, ear orientation, and whether they are trying to put distance between themselves and the equipment. Reading body language closely also lets you spot physical problems early, like rubbing under a chest strap or repeated scratching that suggests an ill-fitting harness pinching somewhere it should not.

A wellness exam is a great time to assess fit and comfort, and our preventative care visits include a check of how the gear you are using actually fits your pet- just ask us.

Why Do We Recommend Reward-Based Training?

The science is unambiguous: positive reinforcement training is more effective, more humane, and more durable than methods built around pain or fear. It also avoids the equipment that comes with those methods, which is the part that matters for this blog.

Here’s a practical example:
Suppose your dog pulls hard on leash. The “old-school” approach is to pop a prong collar on so that pulling causes pain and the dog learns to stop pulling. What actually happens is that the dog learns “pulling hurts” but does not learn what to do instead, and they often associate the pain with whatever they were looking at when it happened, which can become other dogs, kids on bikes, or the mail carrier. That is how you turn a pulling problem into a leash reactivity problem.

The reward-based approach uses a front-clip harness or properly fitted flat collar, a high-value treat, and a structured game like the engage-disengage game where your dog learns to look at a trigger and then check in with you. It takes a few weeks, but the result is a dog who actually wants to walk politely instead of one who has been physically suppressed into doing it. We are happy to walk you through training resources during a visit. Just reach out.

Training Devices to Avoid

Prong Collars and Choke Chains

Prong collars work by digging metal points into the neck when a dog pulls. Choke chains tighten down with the same goal: pain to suppress pulling. Beyond the welfare concerns, the dangers of training collars include real physical risks: tracheal trauma, esophageal injury, neck strain, and damage to the soft tissues around the throat. Sudden lunges (a squirrel sprint, a startle response, anything) can cause acute injuries that range from bruising to fractures of the small bones in the neck. None of these tools teach the dog what TO do, only what hurts. These are especially dangerous for pets who already have tracheal diseases, like small and flat-faced dogs.

Shock Collars and Other Aversive Tools

Shock collars (rebranded as “e-collars” in modern marketing) deliver electric stimulation as a punishment. The medical concerns include burns at the contact points, particularly when collars are left on too long or set too high, and the behavioral concerns are arguably worse. The body of research on aversive training methods consistently shows increased fear, anxiety, and even aggression compared to reward-based methods. Punishment can suppress a behavior temporarily, but it often creates new behaviors that are harder to fix, especially in pets who are already anxious.

Retractable Leashes

They seem like a great idea, but retractable leash risks are real. Retractable leashes encourage pulling (the only way the dog gets more length is by pulling against the spring), reduce control to almost nothing in an emergency, and use thin cords that cause real injuries. Retractable leash injuries include rope-burn lacerations on hands, fingers severed when wrapped in the cord, and dogs running into traffic before the brake can engage. The cord itself can also wrap around legs, both human and canine, causing burns or ligament injuries.

If you are struggling with pulling or your dog is reactive on walks, please contact us before reaching for one of these tools. There is almost always a better option.

What to Use Instead: Veterinarian-Recommended Walking Equipment

Collars and Harnesses That Actually Help

Harnesses come in two main configurations. Front-clip harnesses (with the leash attachment on the chest) are great for dogs who pull, because pulling redirects them sideways instead of giving them more momentum. Back-clip harnesses are more comfortable for dogs who already walk politely. Head halters can help very strong pullers but require a slow, treat-paired introduction; otherwise dogs can rub their faces raw trying to get them off. For small dogs with tracheal collapse or brachycephalic pets that already have breathing problems, harnesses are the best equipment hands down.

Flat collars are fine for ID and a leash quick-attach in low-pull dogs. Martingale collars are a humane “limited-slip” option for sighthounds and other narrow-headed breeds whose collars can slip over their head. Whichever you choose, choosing the right collar comes down to fit: two fingers should slide between the collar and the neck, with no rubbing or skin folding under the strap.

For most pets, a properly fitted walking harness is the gear we recommend day-to-day. We are happy to do gear fittings during wellness visits.

Standard Leashes and Long Lines

A 4-to-6-foot standard leash made of leather, nylon webbing, or biothane gives the right balance of freedom and control for everyday walking nicely on leash. For recall practice, sniff walks in open fields, or training where you want your dog to have more space safely, a long line of 15 to 30 feet attached to a harness is a far safer alternative to a retractable leash.

This kind of practical, evidence-based equipment guidance is part of what AAHA-accredited practices commit to. Our AAHA accreditation means we meet a set of standards that fewer than 15% of practices nationally meet, and that includes how we counsel clients on humane handling and equipment.

Which Common Toys Are Dangerous for Pets?

We see toy-related injuries every month, and they tend to fall into a few categories. The most serious are gastrointestinal foreign bodies, which happen when a piece of a toy gets swallowed and lodges somewhere in the GI tract. Linear foreign bodies (rope toy fibers, especially) are particularly dangerous because they can saw through intestinal walls. What’s dangerous for one pet may not be a problem for another, so supervision with any new toy and knowing your pet’s play style makes all the difference.

Specific risky toys to watch out for:

  • Rope toys that are unraveling, especially in dogs who shred and swallow the fibers
  • Squeaker toys with disc-shaped squeakers that can become choking hazards once the toy is shredded
  • Undersized toys, including tennis balls in larger dogs, which can lodge in the back of the throat
  • Hard plastic toys marketed as “indestructible” that crack teeth on the way to proving themselves wrong
  • Stuffed toys whose stuffing can be ingested in large quantities
  • Tennis balls, especially covered in sand from beach play, can wear down the enamel on teeth over time

If your pet ingests part of a toy or starts vomiting, retching, refusing to eat, or showing abdominal pain, call us and come in for emergency care  right away. Foreign body removal is one of the most common emergency surgeries we see, and our diagnostics and surgery services include the imaging and surgical capabilities to handle these cases when they happen.

Which Chews and Treats Pose Real Risks?

Chewing is good for dogs, and the right chew can support oral health and provide great mental enrichment. The wrong chew lands them in surgery. The most common offenders are easy to remember:

  • Bones of any kind: cooking makes bones brittle, and brittle bones splinter into sharp shards that can perforate the GI tract. Uncooked bones fracture teeth easily.
  • Rawhide: softens into a thick, gelatinous mass that is hard to digest and can cause obstruction.
  • Antlers and hooves: these cause “slab fractures” of the upper premolars, where a chunk of the tooth literally breaks off. We see this consistently.
  • Hard nylon bones chewed down into sharp points.
  • Any chew worn down to a small nub that becomes a choking hazard.

You can find more detail in AAHA’s list of dangerous chew items.

The thumbnail test: press your thumbnail firmly into the chew. If it does not leave a dent, it is too hard for your dog’s teeth and risks fractures. Chews should have some give.

Safer Toy and Chew Alternatives

Plenty of safe options exist. For chewing dogs, look for:

  • Durable rubber toys, especially the kind you can stuff with treats or peanut butter for added mental engagement
  • Vet-approved dental chews with the VOHC seal of acceptance
  • Edible chews softer than your thumbnail (most commercial soft dental sticks, collagen chews, and rawhide alternatives are good options)
  • Puzzle feeders and snuffle mats for food-motivated dogs

For chewing and dental support, our pharmacy carries dog dental chews and treats selected for safety and effectiveness, including options that are appropriately soft.

Frequently Asked Questions About Pet Equipment Safety

My dog only pulls a little. Is a regular collar still bad?

A flat collar is fine for occasional, gentle pressure on a dog who walks nicely. The risk increases dramatically with chronic pulling or sudden lunges, especially in small breeds, dogs with tracheal collapse risk, and brachycephalic breeds.

Are tennis balls actually unsafe?

For most dogs, supervised tennis ball play is fine. The concerns are: the abrasive felt can wear down enamel over time with constant chewing, and large dogs can get a tennis ball lodged in the back of the throat. Use bigger balls for bigger dogs, and do not leave tennis balls out for unsupervised gnawing.

My dog destroys every toy in 5 minutes. What is safe?

Heavy chewers do best with the most durable rubber and dental options. We can give specific recommendations based on your dog’s chew style and size during a visit.

Are bully sticks safe?

Bully sticks are a moderate-risk middle ground. They are digestible (good) but can become choking hazards once they reach the small-nub stage (bad). Always supervise, and toss them when they get small enough to swallow whole.
