Skip This: Prong and Shock Collars

Why credentialed organizations say no

The American Veterinary Society of Animal Behavior (AVSAB) — the largest organization of board-certified veterinary behaviorists — published a position statement explicitly recommending against the use of aversive training tools, including prong (pinch) collars, choke chains, and electronic shock collars.

The statement is unambiguous: Reinforcement-based methods are at least as effective, and don't carry the documented welfare risks.

The American Veterinary Medical Association (AVMA) echoes this position. Fear Free, the program that certifies veterinarians, groomers, and trainers in low-stress handling, publishes guidance warning that shock, choke, and prong collars can injure the skin, neck, trachea, and nerves, and can make a dog more fearful.

This isn't a contested area in evidence-based behavior science. The dispute exists in:

• Marketing copy
• Anecdotal forums
• Certain internet personalities

It does not exist in the peer-reviewed literature.

What the research actually shows

Multiple peer-reviewed studies have documented elevated cortisol (a stress hormone) in dogs trained with aversive tools. A 2020 paper in PLOS ONE compared dogs trained with positive reinforcement to those trained with shock and prong tools and found higher stress signals, more conflict behaviors, and slower learning in the aversive-tool group.

A recurring finding: dogs trained with aversive tools more frequently develop new fear-based behaviors, including aggression toward the handler.

The irony: The very reactivity these tools are often sold to fix is a documented side effect of using them.

What works instead

On leash pulling: most dogs adjust their walking style within a few sessions when paired with consistent reinforcement.

On reactivity: look for one of these credentials:

• IAABC-CDBC
• CPDT-KSA
• KPA-CTP
• Fear Free Certified

The right professional will work on threshold, counterconditioning, and sometimes prescribe behavioral medication via your vet.

A note on the 'balanced training' marketing pitch

'Balanced training' is the most common rebrand of aversive methods. The pitch is that reinforcement and punishment are tools in a toolbox. The behavior-science consensus is that the alleged tradeoff is a marketing fiction: reinforcement-based methods are at least as effective on the metrics that matter (reliability, generalization, dog welfare), without the documented harms.

Three words worth checking credentials over, if they appear on a trainer's site:

• 'Balanced training'
• 'Leadership'
• 'Corrections'

Most certified organizations exclude force-based methods.

Always consult a certified positive-reinforcement trainer

For any reactivity or training problem severe enough that prong or shock collars came up as a 'solution,' the right next step is a credentialed positive-reinforcement trainer or a board-certified veterinary behaviorist. A directory of Fear Free Certified providers is at fearfreepets.com; CPDT-KA-credentialed trainers are searchable at ccpdt.org.

FAQ

My dog is reactive and 'nothing else works.'

This is the single most common framing in the prong/shock-collar marketing pitch — and the one credentialed behavior consultants hear most often from clients before successful reinforcement-based work. Reactivity is a threshold problem, not a leash-equipment problem. A certified behavior consultant — not a tool — is the lever that changes the outcome.

Aren't 'modern' e-collars different from old shock collars?

The peer-reviewed literature treats the modern stim-mode e-collar as the same category. AVSAB's position statement explicitly covers all variants. 'Stim,' 'tap,' and 'vibration' are marketing language for what the dog experiences as aversive enough to suppress behavior.

What about prong collars used 'correctly'?

AVSAB's position is that there is no use case for prong collars that reinforcement-based methods can't address better. The risk-benefit analysis isn't close.
